Codes specifically not working with GitHub

[ghost]

I noticed that my codes were not working with my Github account. Assuming it was a time sync issue, I tried to perform time correction and received the following error:

There was a problem contacting Google's server. Please check your network settings and try again.

Upon making a new account, I tried enabling 2fa via Google Authenticator again and the codes did not work.

Do codes on the same device work with Google accounts?

Have you tried deleting the GA and re-enrolling it?
