Additional Information

I’m new to github and GitHub Desktop and the web interface is all I’m familiar with. If I choose “Repositort\View on GitHub” the repository opens successfully in a browser window.

Switching to openssl resolves the issue, as does this .gitconfig addition

[http “https://weak.example.com”] sslVerify = false

[shiftkey]

The version of Git embedded in Desktop uses the Windows SChannel APIs for validating certificates as part of the HTTPS handshake. We’ve had various reports of this failing due to other tools being installed alongside, like anti-virus programs. As @j-f1 suggested, see what else you have installed that might be interfering.

As a workaround, you can revert to the classic OpenSSL behaviour by opening the repository in a shell and running these two commands.

$ git config --global http.sslBackend "openssl"
$ git config --global http.sslCAInfo [path to .pem file]

If your GitHub Enterprise server has internal SSL certificates, you’ll need to extract them into a PEM file and put them somewhere on your local machine. Otherwise, the PEM file distributed by the cURL team should do the trick.
