This is an old bug and I am not too sure how it happened...
Under normal bootstrap, we would not go into maintenance mode in such a way that we'd prevent bootstrap from login in into the API server.
I cannot reproduce it and, consequently, cannot guarantee that a fix will work.
If you have repro steps, please share. I'll mark as Incomplete for now.
