If you’re behind a corporate firewall, chances are that you have some trouble using GitHub for Windows against a remote repository. This is because most organizations use some kind of proxy.
Most of the time you get an error like:
We have to tell GitHub for Windows to use this proxy as well. Therefore you have to edit the .gitconfig file typically found at C:\Users\<yourusername>\.gitconfig or C:\Documents & Settings\<yourusername>\.gitconfig.
In the .gitconfig file , add the following lines
git config --global http.proxy http://myproxyserver.acme.com:8080
Most of the time you get an error like:
fatal: unable to access 'https://github.com/wullemsb/asampleapp/': Received HTTP code 407 from proxy after CONNECT
We have to tell GitHub for Windows to use this proxy as well. Therefore you have to edit the .gitconfig file typically found at C:\Users\<yourusername>\.gitconfig or C:\Documents & Settings\<yourusername>\.gitconfig.
In the .gitconfig file , add the following lines
[http]
proxy = http://myproxyserver.acme.com:8080
[https]
proxy = http://myproxyserver.acme.com:8080
As an alternative you can also use the command line:
git config --global http.proxy http://myproxyserver.acme.com:8080
