paul, (edited ) Doing a random check of my server logs, looking for oddities and trouble.
In 'journalctl -u mastodon-web' I see, "ERROR -- : [ActionDispatch::HostAuthorization::DefaultResponseApp] Blocked hosts: <my server IP address>" as shown below.
Does this just mean someone/something is trying to access my Mastodon instance from the IP address and not the host name?
Safe to ignore? Normally the IP forwards to the domain name. I just checked and it does.
