I have the same issue with Eclipse (Neon 4.6 eclipse installer by Oomph 32 bit) as in this question and as explained there I have downloaded the automatic configuration script (the script is set up through the Group Policy so I can’t change my LAN settings) that my browser is using. I used the host and port in the return statement and did as explained below
Select the "HTTP" line and click the edit button
Add the IP address and port number above to the http line:
Does anyone know what else I can try because I am still getting a network problem message?
Your help will be appreciated
Proxy Network problem message:
I have changed the active provider to Manual and retried again, then it worked.
I installed an old version and it's worked well.
this is the link for the old version:

You can download a zip file of the Eclipse package you want and explode it in your filesystem where you want it,
Here is link for Eclipse package for windows:

For me, I had similar issues to this that related to my office network and their use of a security tool called Netskope which needed its root-certificate into the jvm that would be used by the Eclipse installer. I elaborated on my workaround steps in this other thread:
https://stackoverflow.com/a/69171147/1302220
I upgraded from Spring Tool Suite (STS) 3.2 to STS 3.3 and it has brought a few issues with it.
When trying to download plugins, I get "Proxy Authentication Required.." errors.
I have my http proxy configured correctly (the same way as 3.2). I have even compared all the .ini files between the versions and cannot find a difference.
As many posts have suggestion, I have also cleared the SOCKS proxy, and even tried to specify in the .ini files that it is not to be used- but again without any luck.
I have tried configuring the HTTPS proxy and playing with the properties in the .ini files for both, restarts, running under different permissions, ect...
Could use some new ideas on this one.
Thanks a lot for reading.
I had the same problem. It turned out that this was caused by two plugins. To allow your STS to connect to the internet via proxy just delete this two plugins:
org.apache.httpcomponents.httpcore_4.2.4.v201305222326.jar
org.apache.httpcomponents.httpclient_4.2.5.v201305222326.jar
There should be older versions of this plugins so everything should be working fine.
The same thing just happened to me on installing STS 3.4. I could only get the proxy to work by switching my proxy provider to manual, editing the http schema and adding my proxy username and password. Less than ideal.
If I remove STS, the native proxy provider starts working again.
I had to add the following 2 lines to STS.ini file. The first line at the top of the file and the second line at the bottom of the STS.ini file:
-clean
...
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4
Then on the following file, which exists in the STS (Eclipse) installation folder...
configuration\.settings\org.eclipse.core.net.prefs
...I had to enable proxies making sure that the following properties were set to true:
proxiesEnabled=true
systemProxiesEnabled=true
Only after doing this and rebooting STS, the proxy settings I had entered through the UI previously, took effect.
Edit (2020-01-30):
If the file org.eclipse.core.net.prefs doesn't exist, just create with the following basic content. Edit as needed.
eclipse.preferences.version=1
nonProxiedHosts=localhost|127.0.0.1|another-host-in-your-LAN
org.eclipse.core.net.hasMigrated=true
proxiesEnabled=true
systemProxiesEnabled=true

proxyData/HTTP/host=your-proxy

There is an open issue: https://issuetracker.springsource.com/browse/STS-3647
It is recommended to download the latest nightly build.
I'm following the instructions for installing Ardor3D as an Eclipse Project Set via Subclipse; instructions at:
http://www.ardor3d.com/wiki/svneclipsetutorial
I installed Subclipse from
http://subclipse.tigris.org/
and installed fine. If I go to Eclipse's Preferences and Team|SVN I can see that the SVN Interface Client is JavaHL, and hence installed fine.
However, when I come to checkout the code at:
http://ardorlabs.svn.cvsdude.com/Ardor3Dv1
by selecting New|Other|SVN|Check Projects from SVN I get the following error message:
RA layer request failed
svn: Unable to connect to a repository at URL 'http://ardorlabs.svn.cvsdude.com/Ardor3Dv1'
svn: OPTIONS of 'http://ardorlabs.svn.cvsdude.com/Ardor3Dv1': could not connect to server (http://ardorlabs.svn.cvsdude.com)
I know the URL is valid as I can install the above fine on my work m/c of WinXP. However, the same installation on my personal laptop of Win7 fails to connect.
I tried temporarily disabling the firewall and it still fails.
I've tried playing around with the config and server files in:
C:\Documents and Settings\Administrator\Application Data\Subversion
but to be honest not 100% sure as what to change, if anything as I'm not using proxy settings.
If there's an expert out there who's knows the solution to this problem I would greatly appreciate hearing from you.
Thanks
Graham
PS. I find the error message "RA layer request failed" confusing as the URL is valid.
I had exactly the same problem, which turned out to be caused by a proxy server. The solution to my problem was to configure subversion to work with the proxy server, however it was not obvious how to do this.
You should have a directory similar to : C:\Documents and Settings\UserName\Application Data\Subversion
In that directory there will be a file called servers.
I un-commented and edited the following entries and my subversion is now working fine with Eclipse:
http-proxy-host
http-proxy-port
http-proxy-username
http-proxy-password
Why exactly you can't configure this through Eclipse is abit of a mystery, but there you go.
Another user account could login, I got the error as described above. The difference was the Proxy setting which was missing in my account. It is stored per user in the Registry and I could easily change this in the Tortoise SVN config.
We encountered this error with our server. While we were able to successfully access the CollabNet 5 SVN admin console, navigating to the repository to browse it from the admin console would fail. We also were not able to connect from Subclipse clients.
The problem turned out we were not hitting the correct port on the server. We had reconfigured the default port from 80 to 4343 and the admin console reported the changed setting but the server was still running on 80.
For what it's worth, in order for the configuration change to stick, we had to bring the repo server down and make the change in the admin console and then restart the machine. We were then able to browse the repo from the link in the admin console.
I was trying to add the PDT,
Indigo - http://download.eclipse.org/releases/indigo
Unable to read repository at http://download.eclipse.org/releases/indigo.
Unable to read repository at http://download.eclipse.org/releases/indigo.
http://download.eclipse.org/releases/indigo is not a valid repository location.
So what's the correct url ? I went and looked lots of places. Can someone point me to the exact link ?
Edit :
Problem once you go to http://download.eclipse.org/releases/indigo , you will see the below error. So I guess its moved somewhere.
This software repository URL, http://download.eclipse.org/releases/indigo/ , provides access to the software repository for the Eclipse indigo release. Until its released in June 2011, it will contain milestone builds.
The repository site URL is typically pre-populated in the list of software repositories when you install the Eclipse Platform or SDK.
For more information about installing or updating software, see the Eclipse Platform Help.
There is also a collection of handy, downloadable all-in-one zip files available for many interests and platforms. Many people find these all-in-one packages the easiest way to get started.
Can you connect to internet at all through Eclipse?
Open the internal webbrowser. In Eclipse: Window -> show view -> Other -> General: Internal web browser.
Look up any normal adress, is it working?
Can you connect to another update site? Try for example Eclipse Emma:
http://update.eclemma.org/
Do you see anything there?
What are your proxy preferences? Go to Window -> preferences -> General: Network connections.
The active provider:
Specifies the settings profile to be used when opening connections. Choosing the Direct provider causes all the connections to be opened without the use of a proxy server. Selecting Manual causes settings defined in Eclipse to be used. On some platforms there is also a Native provider available, selecting this one causes settings that were discovered in the OS to be used.
If internet is working fine outside of Eclipse, try changing to Native. After that, try Direct.
I have encountered problems where an update site would not load, then I had to remove it and add it again. This forces Eclipse to reread the contents of the site even if it has a cached copy. So, if you still get no connection to the indigo update site, but everything else is working, try that. Go to Window -> Preferences -> Install/update: Available Software sites. Then remove and add the indigo site. Just remember to copy the adress so you can add it again.
As suggested in a comment below by #lostiniceland, this is a simpler way to achieve the above:
Goto Window -> Preferences -> Install Update -> Available Software Sites => select the entry and click the "Reload" button to the right. This is sometimes also helpful when you have a local updatesite for testing custom plugins
I had the same problem and resolved it by
Deleting the cache directory \eclipse\p2\org.eclipse.equinox.p2.repository\cache
Refreshing the repositories.
Preferences -> Install Update -> Available Software Sites => select the entry
Click the "Reload"
Check if you are able to connect to eclipse market place url (http://marketplace.eclipse.org/) from browser. If its working then the issue is because of proxy server using in your network.
We have to update eclipse with proxy server details used in our network.
Go to :- Windows-> Preference -> General -> Network Connections.
And edit HTTP ,with proxy details.
Click OK
Done.
I was having this problem and it turned out to be our firewall. It has some very general functions for blocking ActiveX, Java, etc., and the Java functionality was blocking the jar downloads as Eclipse attempted them.
The firewall was returning an html page explaining that the content was blocked, which of course went unseen. Thank goodness for Wireshark :)
Another way to solve this kind of error is to start eclipse with this argument
-vmargs -Djava.net.preferIPv4Stack=true
Working fine with Eclipse (x64) 4.3.1
Had this problem in Linux, and I found that the user doesn't have permission to update the eclipse directory
change the owner of eclipse folder recursively, or run eclipse with user who has write permission to the folder
In Windows 7 32-bit version, I started the eclipse with as an administrator. This worked for me.
I had the same problem. Try to deactivate your Firewall (I had avast!), which worked for me.
(Sorry for my English I'm French :D)
Please make sure you are using correct url. If You are using url - http://download.eclipse.org/releases/indigo on your eclipse luna(v4.4) then it might be not working in this case you should use - http://download.eclipse.org/releases/luna
I have tried this and its working.
What worked for me:
Since yesterday, I have been trying to install the Eclipse plugin - "Remote System Explorer" from the Eclipse marketplace on a freshly downloaded Eclipse 4.8 as shown below,
and everytime I was getting this error:
Unable to read repository at http://download.eclipse.org/releases/kepler/.
Unable to read repository at http://download.eclipse.org/releases/kepler/201306260900/content.jar.
download.eclipse.org:80 failed to respond
which brought me to this SO post.
I tried a few solutions mentioned here in the different answers like this one and this one and this one, but none of them worked. I just gave up almost, thinking that either the corporate network here is somehow blocking the specific download requests or the 4.8 version of Eclipse is buggy.
Discovery:
I could not reload all the paths under 'Window' -> 'Preferences' -> 'Install/Update' -> 'Available Software Sites'.
Preconditions:
What did work for me from the beginning was:
I could open google.com from the internal web browser of eclipse and,
some of the update paths, I could reload even. (As was mentioned as a possible solution or test, in some of the answers here, like this one.)
Finally, this answer put me on the right track - for my specific case, at least. Just my step was to do the exact opposite of what that answer was doing.
Solution:
I had to change all the http:\\ paths to https:\\ and suddenly it started to work. I don't know who - either IE/Edge on Windows 10 or the Windows 10 firewall or the company firewall is blocking HTTP communications. But with HTTPS, I can finally install plugins from the Marketplace.
HTTPS reload works
I must say, what is strange is that not all the paths required https. Except a few, the rest seemed to have had no problem working with HTTP. But I anyways changed all to HTTPS, just for good measure.
Then reload all the repositories one by one. Press "Apply and close".
Then check for updates. Eclipse will update itself successfully now.
Restart after update.
Finally you can install whichever Plugin you would like to from the Eclipse Marketplace.
Note: In case during the update, this same error pops up again, then see in the repositories that any new paths added by eclipse during the update, are also HTTPS and not HTTP.
Kudos to #Fredrik above. His answer didn't work for me, but lead me to the resolution of my issue:
In 'Window'|'Preferences'|'Install/Update'|'Available Software Sites'. The location that I was attempting to install from the 'Marketplace' was getting inserted with an https:// URL. Editing this to http:// allowed me to then use 'Help'|Install New Software ...' to select the repository from the drop down 'Work with:' combobox instead of having the https:// one automatically inserted and used.
For eclipse, there are normally different options available:
If you want to use the PHP development environment (only), you should go with the corresponding distro of eclipse. There is a distro for PHP provided by Zend.
You may add PDT to an indigo release by doing the following steps:
Check if an update site for PDT is included in your eclipse installation:
Open the Help > Install New Software dialog.
Click there on the link Available Software Sites.
In the list, the URL http://download.eclipse.org/releases/indigo should be marked.
Close the dialog.
Select from the Work with list the site with the right URL.
Enter in the filter box PDT and search in the list for the PDT tooling you want to install.
Install the PDT tooling.
If that does not work, you may download a complete update site from the PDT project site.
Visit the site (URL above).
Click on downloads.
Search there for the string "all in one update site".
Download the zip file.
Install it in your Indigo installation. Help > Install New Software > Add... > Enter name and select from button Archive the zip file
I hope some of the installation instructions will work for you.
This is the correct URL. Chances are Eclipse cannot read it properly because of the Internet connexion.
Are you using a proxy to get Internet access? If this is the case you need to notify Eclipse via the "Preferences/General/Network Connections" menu.
That URL works fine. The message you report is normal when you look at it in a browser. My copy of Eclipse has no problems talking to it. If yours does, I suspect a proxy configuration error in your copy of eclipse.
Also try it by turning off the firewall, and similar services. It worked for me!
If you can't access https://dl-ssl.google.com/android/eclipse/ simply
try to use http://
instead of https://
I spent whole my day figuring out this and found the following. And it works great now.
This is basically an issue with your gateway or proxy, If you are under proxy network, Please go to the network settings and set the proxy server settings(server, port , user name and password). If you are under direct gateway network, your firewall may be blocking the http get request from your eclipse.
I was also unable to read the repository. Even after the disabling most of the entries under Available Software Sites things were still not working.
I had no proxy to worry about and even disabling the firewall (which I do not recommended) as a last resort did not help.
Viewing the error log, from the dialog box which Eclipse displayed, there was mention of a cache directory under .eclipse in my home directory. I deleted the two cache directories I found and Eclipse was working again.
For my setup the two directories I deleted were:
.eclipse/org.eclipse.platform_4.4.2_119745494_macosx_cocoa_x86_64/p2/org.eclipse.equinox.p2.core/cache
.eclipse/org.eclipse.platform_4.4.2_119745494_macosx_cocoa_x86_64/p2/org.eclipse.equinox.p2.repository/cache
NB: My setup is Eclipse Luna 4.4.2 running on Mac OS X Yosemite 10.10.3
In my case, I discovered that the major issue why my eclipse won't connect to internet is my Internet Service Provider. I was only able to browse some websites but unable to browse other website. Fixing the issue with the ISP worked.
My issue was the Eclipse Marketplace client needed updating.
After trying Fredriks solution of
Go to Window -> Preferences -> Install/update: Available Software sites. Then remove and add the indigo site. Just remember to copy the adress so you can add it again.
The Marketplace client wouldn't load. But I could access it via a browser.
So, I went to the Help -> Eclipse Marketplace
it loaded fine
Clicked on Installed and found the Eclipse Marketplace Client and it had so i clicked it it updated and then when I did the standard update everything worked.
Sometimes, there will be firewalls and restrictions in the network preventing the plugin to get downloaded. We can try some other network. This actually resolved my issue.
I was facing the issue while adding team explorer plugin to eclipse from https://marketplace.eclipse.org/content/team-explorer-everywhere.
Used team explorer plugin for ecplise for internal use of xamarin for mac.
Error:
unable to read repository at http://marketplace.eclipse.org/content/team-explorer-everywhere
org.eclipse.equinox.p2.core.provisionexception unable to read repository
Unknown host exception
Goto https://github.com/microsoft/team-explorer-everywhere/releases
Download: TFSEclipsePlugin-UpdateSiteArchive-14.135.0.zip
From Eclipse->Help->Install new software.
From Add Repository window select Archive select the downloaded zip file.
Continue installation.
Also try if in the eclipse paths there is some duplicated
Luna - http://download.eclipse.org/releases/luna
Luna - http://download.eclipse.org/releases/luna/1234567...
Try both of them, one may work.
In my case, with 2 eclispes installed, in one of them the path
Luna - http://download.eclipse.org/releases/luna
works, in the other one, i must select:
Luna - http://download.eclipse.org/releases/luna/123456...
In both the internal browser can access to internet. Both are Luna (but one is RCM, the other one i don't remember).
No meu caso era o anti-vírus que estava bloqueando a conexão do eclipse, desativei o anti-víruse tudo funcionou o//.
Translation:
In my case it was the anti-virus that was blocking the connection from eclipse. I disabled the anti-virus and everything worked.
I'm trying to add this repository to Eclipse (Indigo):-
http://download.eclipse.org/releases/indigo
Seems okay when checked in a browser, but I keep getting "unable to connect" in Eclipse, and when I check the URL Eclipse is apparently looking for:-
http://download.eclipse.org/releases/indigo/content.xml
in a browser, I get a "404 not found". The locations for previous releases (e.g. galileo) don't seem to be there either. Have they moved? Am I misunderstanding something?
I tried some of the suggestions in this previous thread:-
Eclipse updates not working
But they don't seem to work (and I'm not using a proxy anyway).
Hemdoar
This worked for me:
Open terminal. Navigate to Eclipse folder.
sudo nano eclipse.ini
at the bottom, add this line in:
-Djava.net.preferIPv4Stack = true
Then ctrl+O to save, ctrl+X to close (it says at bottom). IPv4/IPv6 problems? Solved.
Then delete the cache VonC said to:
<eclipse>/p2/org.eclipse.equinox.p2.repository/cache
(This can be done using "sudo rmdir /p2/org.eclipse.equinox.p2.repository/cache" or by typing "sudo nautilus" into terminal, to open a root-priveleged filesystem browser, than navigating to, selecting the folder, and pressing the delete key). Then restart eclipse, goto Help>install new software>available software sites
Make sure the repos you want (such as "http://download.eclipse.org/egit/updates/") has a "/" right at the end. If it doesn't, delete that entry, and create a new, identical one which does, because Eclipse won't just let you edit it and click ok. Then click ok, and from the combo box choose e.g. the egit link, and lo, it will find it.
Still not working? Window>show view>internal web browser; check it can access internet. Hope that helps!

VonC Sep 14 '11 at 6:03
I used VonC's answer to good effect. I also uninstalled a program called webroot. I think this had something to do with it because other programs were also having network problems.
This is because windows IPV6 issue. Try adding the following VM option in the eclipse.ini
-Djava.net.preferIPv4Stack=true
Can you connect to internet at all through Eclipse?
Open the internal webbrowser. In Eclipse: Window -> show view -> Other -> General: Internal web browser.
Look up any normal adress, is it working?
Can you connect to another update site? Try for example Eclipse Emma: http://update.eclemma.org/ Do you see anything there?
What are your proxy preferences? Go to Window -> preferences -> General: Network connections.
The active provider:
Specifies the settings profile to be used when opening connections. Choosing the Direct provider causes all the connections to be opened without the use of a proxy server. Selecting Manual causes settings defined in Eclipse to be used. On some platforms there is also a Native provider available, selecting this one causes settings that were discovered in the OS to be used.
If internet is working fine outside of Eclipse, try changing to Native. After that, try Direct.
I have encountered problems where an update site would not load, then I had to remove it and add it again. This forces Eclipse to reread the contents of the site even if it has a cached copy. So, if you still get no connection to the indigo update site, but everything else is working, try that. Go to Window -> Preferences -> Install/update: Available Software sites.

Goto Preferences -> Install Update -> Available Software Sites => select the entry and click the "Reload" button to the right. This is sometimes also helpful when you have a local updatesite for testing custom plugins
first resolve proxy conflicts and if then too eclipse is not getting connected to internet *turnoff your firewall/antiviru*s and try again
To resolve proxy conflicts:Go to windows->prefernces-general tab->network settings
if you dont use proxy settings, cgange native to direct
if you use proxy, chenge native to manual and fill details of proxy for http and https by pressing 'edit' and clear SOCKS tab by pressing 'clear'
check if your SOCK is disabled on operating system too. or doing it open to 'Internet options' dailog box. Go to connections and press lan connection. press 'advanced' button ans clear the textboxes in front of 'socks' and uncheck the msg saying 'use same address for other network protocols'
I did this and worked for me
If you are using Fiddler2 (or any other web sniffer/debugger tool), it may be your problem, as it acts as a local proxy.
Sometimes, even if its not running, I find myself obligated to start it and disable traffic capture.
Hope that helps!
