I have searched for this and found answers that do not work in my case. I would appreciate some thoughts on this
I have set up a github page at: https://ir-ischool-uos.github.io/mwpd/
Some users reported that when they visit the page, an error about security is displayed, like this on Chrome:
- However, many users say it works ok for them.
I have found some sources say that this only happens if your link contains 'https' instead of 'http', but tested on two computers, one mobile phone and one tablet they both work fine. I also found source that say I should use GitHub page's https support, and I checked my setting this already is ticked.
Is there anything I can do to fix this for every user?
Thanks
This error could happen because of numerous of reasons. For example:
The server certificate (or at least one of the certificates in the chain of trust) is not among the trusted certificates that the browser/system maintains (maybe an outdated list?). Try to update the browser/system.
The date/time on the system is not configured correctly.
The connection is being intercepted (by an attacker?) and the certificate is manipulated, hence the SSL connection handshake process could not complete.
Your connection is not private error appears on websites using the SSL / HTTPs protocol when a browser is unable to validate the SSL certificate issued by the website.
Basically, any website using SSL / HTTPs protocol sends a security certificate information to users browsers upon each visit. Browsers then try to validate the certificate using the public key accompanying the certificate.
If it checks out, then users browser encrypts the data using the private key sent by your website. This encryption secures the data transfer between a user’s browser and your website.
I have checked it accross 3 different connections and they all worked just fine.
I believe the problem could be from the users. They may need to clear their cache, check if their clock is set correctly, their antivirus could be stopping it. And their browsers may be outdated.
What I will advice is just (https://support.github.com/contact). They could check to verify if this is an issue from the server or not.
But from what am looking at, this may be an issue with the user's device.
Also here are a few links you could refer and see if all settings on your own part are rightly set;

I hope this helps. Let me know!
If you are using a school/college wifi, most probably someone has your credentials and he/she is using it at the same time as you so basically when he/she is using the web you'll get this message, you should probably change your password or switch on VPN.
If the WiFi/other network used to access the website in question is a school or public network, some 3rd-party software used by it's administrator might be trying to prevent or override the connection to your website.
That might happen in order to display an error message (e.g. "Website access prohibited"), a captive portal (network login window), or just to watch the data being sent around.
Since you're using HTTPS it was prevented when the certificate check failed, because with HTTPS in place that software has no way of presenting it's own page or eavesdropping, other than creating it's own certificate with your website name in it on the fly. Which, of course, was rejected by the browser, since either the user didn't expect it, or, if it's indeed a school/company network, the PC wasn't properly enrolled for use on the said network.
Either way, there is no problem with your webpage itself. Because Github manages the server for your Pages, chances you could create something causing that problem yourself are pretty much zero.
Sometimes it happens because of the wrong IP/DNS settings. Checking the below places might help resolve the issue:
Make sure you are using a common public DNS server. How to check the DNS server you are using depends on your operating system. Moreover, if you are using a VPN client and it has a DNS configuration, check that setting too.
Check if there is an IP address associated with GitHub in the system's hosts file. In Linux and macOS you may use sudo vi /etc/hosts. If there is one, turn that line into a comment by adding # at the beginning of the line. Save, exit, and check if you see that error again. Do step 3 only if you are still getting the same error.
Go to https://www.ipaddress.com, search for github.io, and add its IP address at the bottom of /etc/hosts file like this example: 140.82.114.4 github.io.
Hope this helps.
I bought my domain from domain.com and now I pay $360pa for inmotionhosting VPS. I just bought SSL for my website for another $125 so I could set up example.com as https://example.com as a legitimate Facebook App.
This was my intention. Maybe I was an idiot.
I want visitors to example.com to arrive at apps.facebook.com/example. This is my website. Naked, it's not good enough.
My nameservers from domain.com point to inmotionhosting.com where my files and database are located. You can only visit by going to example.com.
So how do I have my visitors type 'example.com' in their browser and arrive at apps.facebook.com/example when the entirety of my site is inside that app?
It's either easy or impossible. Maybe the https has given me new powers that I'm not aware of. I know I could set up my canvas files on a different website (its going to be cloaked anyway), but I don't think my https will work without the relevant website. I don't want to wait another week or pay another $125.
So,
How do I redirect to apps.facebook.com/example from example.com?
Assuming your VPS is a Linux box:
http://httpd.apache.org/docs/current/mod/mod_rewrite.html
I would like to block the access to my website while I make changes to it. But I want some selected people and myself to have access to do tests. I found this method which is good (http://25yearsofprogramming.com/blog/20070704.htm), except for the fact it is based on ip addresses (I don't know the ips of everyone and can't ask).
How can I do the following:
- redirect all urls to a page like maintenance.php
- on that page, there is a form that people can use to enter a code
- if the code is valid, the redirection stops and they have access to the website normally
Thanks
If you dont want to use ip addresses you can setup htaccess with passwords for the your testers and everybody else will be redirected.
This site can help you with that: http://tools.dynamicdrive.com/password/
I work for a company which has its own web server they are due to have a complete power blackout over the weekend, meaning their servers will be down.
Does anyone know a way we could present a down status on a maintenance page or some kind of redirect so we can at least inform our users that the site is down for maintenance and not just missing/broken?
The best way is probably setting up a redirection to dummy server on your load balancer or border routers. If you have no such thing, then you can either try asking your provider about the options, or temporarily change the DNS record, provided that you reduce DNS cache timeouts before and after the change, so it takes effect immediately.
Set up a server on another location and point their domains DNS record to that server during the blackout.
The redirect has to be carried out by the web server. No web server, no redirect. What you can do is to get another web site by a web hosting company (which will not be subject to your blackout), and configure it to route requests from your main dns to the temp site with just a plain notice html page, then remove it once power is restored. This can be done if you have the dns info from the primary site. You could also mirror the site this way, and then shut down the mirror and no one will be the wiser. Try http://siteground.com I have used them for years.
If you are using a load balancer, see if it supports a "Sorry Server" page. Most of them have this feature built in.
I am trying to send emails from Django using an email configured by Google Apps, my configuration at the settings.py file looks something like this:
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'contact#mydomain.com'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
When I try to send an email using:
from django.core.mail import send_mail
send_mail("Happy new year", "We wish you the best for 3001",
"contact#mydomain.com", ["someuser#gmail.com"])
I get the following error:
SMTPAuthenticationError:
(535, '5.7.1 Please log in with your web browser and then try again.
Learn more at
5.7.1 https://support.google.com/mail/bin/answer.py?answer=78754 k2sm758604obl.14')
Since I'm working on a remote server with no graphical user interface, I cannot even try to login from the browser.
Just go to
https://accounts.google.com/DisplayUnlockCaptcha
and click "continue". This is going to allow access from other servers.
I've been messing with this for a couple of hours within a cucumber/capybara/selenium test - discovered something stupid which will fix this error for good, guaranteed
The all too familiar error:
Please log in via your web browser: https://support.google.com/mail/accounts/answer/78754 (Failure) (Net::IMAP::NoResponseError)
As it turns out, there are TWO "Allow Less Secure Apps" toggles which need to be changed to allow logins from unknown devices/IMAP.
One here: https://myaccount.google.com/security?pli=1#connectedapps (bottom of the page)
And one here: https://www.google.com/settings/security/lesssecureapps
BOTH OF THESE GODFORSAKEN TOGGLES need to be changed to get rid of this error message.
edit: from user Milothicus (https://stackoverflow.com/users/3538026/milothicus): in myaccount.google.com, under 'Sign-in & Security', select 'Connected apps & sites'. this also has an option to 'Allow less secure apps'. after turning this one on, my server could now send me an automated email.
When I tried to access my account I was sent this email consisting of this link.
https://www.google.com/settings/security/lesssecureapps
You can turn-on then possibly turn-off after you've done testing.
I got the following response from Google Apps support:
You need to turn on your Outbound relay. To do this:
Log into your account at google.com/a/yourdomain.com
Click the Settings tab and then select Email in the left column.
In the Outbound relay section, select Allow users to send mail through an external SMTP when configuring a "from" address hosted
outside your domain.
Click Save changes.
They also provided a help link: http://support.google.com/a/bin/answer.py?hl=en&answer=176054
After turning on Outbound relay and using the proxy to login to the webmail one more time (thanks to #DaniloBargen and #joshcartme) the issue was resolved. I've read the link explaining what the Outbound relay is and I'm not really sure why would I need it (I don't believe I'm using an external SMTP server).
Since I'm not really sure this is what solved the issue I won't mark the response as accepted until I get some confirmation.
Set up an ssh tunnel to the server in question so that you could, from your home computer, log in to the gmail web client using the server's IP. You probably need to tunnel port 80 and port 443, maybe just 443. After logging in through the web client the problem should go away according to knowledge base article listed in the SMTPAuthenticationError.
Here's an example of how to set up the tunnel:
http://www.noah.org/wiki/SSH_tunnel#simple_port_forwarding_.28SSH_tunneling.29
Option #1 (this worked for me):
After getting the error Please log in with your web browser and then try again. Learn more etc. when trying to send email from my web application, I logged in to the email via browser from my local computer.
After I logged in, there was a yellow notification bar on top which asking me if I want to allow external application access my mail. I confirmed this and Google asked me to log in to the account from the application within the next 10 mins. This will white-list the application.
Option #2:
If Option #1doesn't work for you, try this: http://www.rocketideas.com/2012/05/gmail-error-password-not-accepted-from-server-solved/
etusm provided two locations to turn on less secure apps:
One here: https://myaccount.google.com/security?pli=1#connectedapps
(bottom of the page)
And one here: https://www.google.com/settings/security/lesssecureapps
both were turned on, but my headless server still couldn't send me an email. based on JohnPang's google+ recommendation, i found a third location where i had to allow access to less secure apps:
in myaccount.google.com, under 'Sign-in & Security', select 'Connected apps & sites'. this also has an option to 'Allow less secure apps'. after turning this one on, my server could now send me an automated email.
I found the solution at: https://support.google.com/accounts/answer/185833?hl=en and finally https://security.google.com/settings/security/apppasswords
If you are testing your project on a local machine, you should go to the latter link, and enable "Access for less secure apps".
Do you have two factor authentication enabled for the apps account ? Then you might need to use an application specific password for that application.
All of the above doesn't help in my case (weird). But this link might help you:
https://security.google.com/settings/security/activity
You can access it via Google Plus
Open Google+
Select "Security" from the top
Under "Recent activity" click "View all events"
You will see a list of "Unusual Activity"
It shows "Application / device sign-in attempt (prevented) Singapore" as I'm using AWS from Singapore
Click on "Change" > "Yes, that was me!"
Retry again. Done!
As of now (look at my post date) there is only one "Allow less secure apps" toggle in the Gmail account admin UI:
https://myaccount.google.com/u/0/security#connectedapps
It'll work from your local computer (Mac or PC) after that.
To allow access from Amazon EC2 (and I suspect other Cloud-located hosts), there is yet another flag to set in Google's never ending battle with spammers:
https://accounts.google.com/b/0/DisplayUnlockCaptcha
Recently, I have found that this issue can be resolved by confirming that the activity has originated from a request I initiated, by visiting Google Account
I had to confirm, under Security Events, that the suspicious activity was in-fact me, even though the originating server from where the request came from was cloud hosted, and therefore over 1000 km away. After clicking this step, and setting less secure apps, I was able to use getmail to retrieve my mail, over ssl using either imap or pop.
Just want to highlight Danilo Bargen's comment:
An easier way to connect to the other network using tunnels is to use a dynamic tunnel (ssh -D 6789 remotehost) and then to set localhost:6789 as SOCKS5-Proxy in Firefox. Then you are basically in the remote network with your browser and localhost is the remote host
Also I want to add that SOCKS Proxy method also works with Chrome. As a result you can log in with your local web browser as if you are on a server.
change your settings at https://www.google.com/settings/security/lesssecureapps so that your account is no longer protected by modern security standards.
This is occuring due to some apps are marked as less secure apps by google. So to use those apps, you need to give access for those apps. to do that follow http://www.codematrics.com/your-imap-server-wants-to-alert-you-to-the-following-please-login-via-your-web-browser-gmail/
Hope this will solve your issue.
In my case, when i tried to login to the google account via web, it asked me for a captcha. I entered the captcha and then the automation worked.
