Github SSL certificate problem

I get the following message in windows command prompt:

D:\Github\UnrealEngine>git fetch upstream
fatal: unable to access '': SSL certificate problem: self signed certificate in certificate chain

This was working previously. Not sure if this is a local or server issue.

Try updating your git maybe. Github recently changed things about the authentication.

It appears my Anti-Virus program is interfering with git. I had to pause protection and start a new console window to get it to work. I also updated my git for windows. It is working now.
