Protocol https not supported or disabled in libcurl using Git

Question

I have a few github repos and they have been working fine for the last few months.
However, a few days ago I started getting a strange error when trying to push
and pull

Answer 1

I had the same error on macos and homebrew. When i tried-> git clone ... the return was:

fatal: unable to access 'https://github.com/....': Protocol https not supported or disabled in libcurl

I did:

rm '/usr/local/bin/git'

as it mentioned on:

brew link git    

Then i did a git clone again and a keychain popup box appeared and cklicked accept.Then it worked.
