I installed Github for window and I can't connect to my git hub account.
I tried to reinstall several times, but I always end up with the following error:
login failed
Unable to retrieve your user info from the server. A proxy server might be interfering with the request.
I don't use a proxy and I disabled the windows firewall without success. What am I missing here? Am I suppose to NAT a port on my router?
Update the latest .NET Framework 4.5.1
Her is the url : .NET 4.5.1 download link
The error message is really misleading. The issue wasn't linked to a proxy configuration.
After running the DOS command line sfc /scannow, I've been able to find the source of the problem. It turned out that one of my Windows dll (rasman.dll) was corrupted. I replaced the dll and now everything is back to normal.
If updating the .Net Framework and running sfc /scannnow does not work, try to re-install the GitHub for Windows app, make sure that you uninstall it completely by manually erasing the following directories:
- %LocalAppData%\GitHub
- %AppData%\GitHub

Please update your .NET framework .. This will solves the problem ..
I also faced the same problem. Meanwhile I installed the Microsoft Visual Studio Professional 2012 which updates the .Net Framework itself ..
Unfortunately the problem solved ..
A few people have posted saying that other recommended solutions did not help.
I found one machine that was reproducing this error message, even after attempting all of the solutions posted so far.
It turned out that someone had installed AVG with some restrictive firewall settings. Setting the firewall to "Allow All" or "Interactive" modes allowed me to log in.
