How to resolve "git pull,fatal: unable to access 'https://github.com...\': Empty reply from server"

I resolved this problem. I think it happened maybe because of https but I am not very sure. You can Switch remote URLs from HTTPS to SSH.

1.Pls refer to this link for details:https://help.github.com/articles/changing-a-remote-s-url/

Also I had to config the ssh key.

2.Follow this:https://help.github.com/articles/generating-ssh-keys/

I came across this problem because I replaced my mac, but I do the transfer of data,I think it is probably because the key reasons.

I was stuck in this problem until I noticed that I was not logged into my VPN.

1. If you have configured your proxy for a VPN, you need to login to your VPN to use the proxy.

2. to use it outside the VPN use the unset command:

   git config --global --unset http.proxy
   

And remember to set the proxy when within the VPN.

On Windows:

Go to Win -> Control Panel -> Credential Manager -> Windows Credentials

Search for github address and remove it.

Then try to execute:

git push -u origin master

Windows will ask for your git credentials again, put the right ones and that's it.
