I use Git with Visual Studio 2017. Since yesterday every time I try to push or pull from the remote repository with Team Explorer I get the following error:
This is very likely due to GitHub turning off versions of TLS older than 1.2. Visual Studio 2017 and Git for Windows have both been updated. More information can be found here:

Hope this helps!
