Consolidated 404 issue thread in versions since 2.2.1

@tam481 thank you for this. This does not seem to be a complete configuration, as prometheus and grafana configuration are missing. Without prometheus and grafana I was able to get it up and running with minimal changes (removed the auth middleware and I do not have the certs) and I cannot reproduce the issue - have not seen a single 404 everything seems to be running as intended.
