Solutions

1. Read the git stderr shown in the message for the exact failure (missing ref, auth error, network problem) and fix it.
2. Fetch the remote ref first (`git fetch <remote>`) so `git rev-list` can compare the local and remote commits locally.
3. Check network connectivity and credentials to the remote, then retry the push.
