eclipse market place connection issue - eclipse

I have issue in connecting to eclipse market place from Eclipse Version: Oxygen.3a Release (4.7.3a)
I am getting below error when try to open eclipse market place.
"Cannot open Eclipse Marketplace
Cannot install remote marketplace locations: Connection failed
This is most often caused by a problem with your internet connection. Please check your internet connection and retry.

have tried changing window-->preferences-->General-->Network connections-->active provider to Direct/Manual, updating eclipse.ini with "-Djava.net.preferIPv4Stack=true"..
None of the things worked out for me..
Please suggest me on this.
Thanks

The point in the comment is well-taken. I find it hard to understand why so many people at my company are still trying to get Oxygen to work.
However, it is within the realm of possibilities that you can get the Marketplace connection working with this. I would assume that you are running behind a corporate firewall. There will be a particular proxy url you're supposed to use behind the firewall, which you have to configure in "Manual" mode in Network Connections. If you don't know what that proxy url is, you won't be able to get this to work.
Once you get the proxy working, you may get a different error, related to SSL and certificates. That would imply that your firewall requires a particular root certificate provided by your company. Assuming that's the case, that certificate needs to be installed in the Java distribution that is being used to run Eclipse. If you run into this, I would post a new question if you're unable to resolve this.

Eclipse SVN error "svn:E210003:connection refused by the server"

I am using eclipse Juno Service Release 2, and I am trying to connect to a SVN server via SVN Repository Exploring perspective but I get an "svn:E210003:connection refused by the server" error.
I tried the suggested solutions to modify Active Provider to "Manual" and "Native" also in Network Connections from Window->Preferences but I still face this issue. Please take note that I am not able to access command prompt due to insufficient privileges and also the credentials work for one of my colleague, so I just think it might be a proxy issue.
Could you please suggest how can I solve this issue or what to investigate further more?
You likely have to be given permission to connect to the svn server by whoever is acting as its administrator.

Eclipse unable to connect to internet when using a VPN

Eclipse is unable to connect to the internet when I am using a VPN.
The VPN I am using is: https://www.privateinternetaccess.com/
I have no issues when I try browsing the web using the VPN.
If I try to do something like access the Eclipse Marketplace I get an error saying connection fails and it suggests I should check my internet connection and retry.
I have tried restarting eclipse many times. I have tried changing my network connection preferences in eclipse (Direct, Manual, Native).
I don't really understand why connecting to a VPN should have any effect on eclipse.
Maybe, you have not set proxy (and login credentials) in the eclipse.

eclipse kepler "Cannot install remote marketplace locations"

I have downloaded the latest eclipse version, eclipse kepler.
But when i try to access the Marketplace inside eclipse or try to install ADT plugin for Android, it gives me this creepy error which is driving me crazy:
Cannot open Eclipse Marketplace
Cannot install remote marketplace locations: Connection failed
This is most often caused by a problem with your internet connection. Please check your internet connection and retry.
Unable to read repository at http://marketplace.eclipse.org/catalogs/api/p.
Connection reset

Connection reset
please put below line to eclipse.ini in the last it worked for me
-Djava.net.preferIPv4Stack=true
I figured out finally that:
Avira Anti-Virus Software was blocking the network requests by eclipse.
After deactivating "enable web protection" in the Anti-Virus,
the stupid Eclipse was able to update itself.
If you are sitting behind a corporate network it could be filtering out requests coming from eclipse. Switching to 3G on my phone made it work for me.
This frustrated me for a while before I stumbled upon this link:
https://www.eclipse.org/forums/index.php/t/783720/
It says clear SOCKS entry in Network connections and be in manual Active Provider.
The SOCKS entry was already clear but after clicking on clear again, it just worked so worth a shot.

Eclipse does not connect to any update site but internal browser does work

I tried to configure Network Connections but it did not work.
Eclipse's Internal Browser opens all update sites normally.
In IE and Firefox trere are no proxy configuration, but sometimes they request my windows username and password before browse a page. Perhaps there is a transparent proxy, I don't know.
The error:
Unable to connect to repository http://download.eclipse.org/releases/indigo/content.xml
Unable to connect to repository http://download.eclipse.org/releases/indigo/content.xml
Connection timed out: connect
Those links 404 meaning the other end is having problems
Edit - I was wrong, apparently this is an ongoing issue
One potential fix is to set
-vmargs -Djava.net.preferIPv4Stack=true
in your eclipse startup.

Eclipse Remote System Explorer problems

I just installed this plugin in Eclipse Indigo, hoping to have a nice and clean way to access FTP and SSH sites while working in Eclipse.
However, I cannot connect to neither SSH nor FTP sites. I'm sitting on the same computer, connecting to FTP and SSH with FlashFXP and Putty without troublw. But when I put these servers into connections in the RSE in Eclipse, I get connection refused errors when trying to access the servers/sites.
SSH gives this error:
java.net.SocketException: Permission denied: connect
FTP gives this error:
Operation failed with exception
'java.net.SocketException: Permission denied: connect'
There is no error in the console when selecting "Connect" for the connections - the errors pop up when I try browsing "My Home" or "Root" for the connection.
Any ideas? I am working through a Cisco AnyConnect VPN connection, but since I can FTP and SSH with other clients, I find it strange that Eclipse won't let me.
Change the proxy setting to direct connection, because eclipse uses default proxy. so change it to direct.
I had the same problem and after days of searching i found the only solution is reverting to Java 6,
Java 7 was causing all these errors
like everything free you are left on your own with no support
Even though I solved the problem, I am back to using Dreamweaver, the support alone is worth the money
