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.
How could we tell you about an IP inside your own network? Look at the host using that IP and see what’s running on it.
Well it is definitely specific to Lemmy, I selfhost over 20 services and only Lemmy gets pinged on midnight. The only other service I saw doing this was Nextcloud, Nextcloud instance needs to reach itself, but for Lemmy it is a different IP, which is puzzling me
