Based on your question I experimented a little. I changed the base_url to exclude the hyperkitty/ at the end, so just https://udfcd-lists.org/mailman3/
With this I get a similar *looking* set of error lines in the log but now instead of an authorization error it's a "was not found" error, so I think the base_url is correct.
This looks like a permissions problem related to the API - maybe I don't have a key set properly somewhere...?
