Hi all, I selfhost private instance of Lemmy for my friends behind Pangolin reverse proxy. I noticed something interesting in the logs; Lemmy specifically gets pinged / tried to access each midnight UTC from what looks like an IP from inside the network. Just out of curiosity, do you have any idea what that could be? I have federation off and private instance on, but maybe it is something from Lemmy network checking if my server is alive? Thank you in advance
Update: So it turns out I was perhaps correct with my hunch. The local IP turns out to be the proxy I set for ports 80 and 443 (it was internal Wireguard IP). Unfortunately my current setup did not allow me to catch which IP the request came from (which is a problem I have to solve later) but the lemmy-proxy container got requests for GET /.well-known/nodeinfo and GET /nodeinfo/2.1. So it is probably something checking my server, likely from the Lemmy network.
Is your server running on UTC? Depending on your location midnight UTC could also be 8 AM and it could be a user with a very regular morning schedule.
Only you can find out which machine is sending this request…
My timezone is CET, so I get the ping on 2AM. The Lemmy container should be on UTC as I did not specify the timezone when launching the container. It is definitely not human, as the ping comes exactly on midnight UTC, or seconds away from midnight. I will turn off the Pangolin auth and investigate further this midnight. Again sorry for not providing more information, I was certain that it is a thing internal to Lemmy and I was just curious what it is
