I'm not the original submitter, but I also encountered this today when running certbot for the first time. I've attached the relevant portion of the log. It looks like the *actual* problem was a 404 from the Let's Encrypt server, causing a Python exception, but that got replaced by a different exception due to a bug in the Certbot code meant to display the original one.
I re-ran the same Certbot command and it worked the second time, so the 404 seems to have been a transient problem. It may have been the problem described here: https://community.letsencrypt.org/t/occasional-no-such-authorization/191497
