But, the error I got above is different than what happened in the workflow:

remote: fatal error in commit_refs
To <https://github.com/OpenVoxProject/openvox-server>
 ! [remote rejected]     main -> main (failure)
 ! [remote rejected]     9.1.0 -> 9.1.0 (failure)

So, I think you may be right: GitHub just chose a very poor time to be on its bullshit.
