Backup to Nextcloud no longer working

[Taomyn]

After rebuilding my firewall and importing my old config, I have noticed for many months that the backup to my Nextcloud server is no longer working. My fault for not keeping an eye on it and fortunate I had exported settings manually beforehand, but I looked at the firewall logs and I'm seeing this:

The Nextcloud server is on my local LAN but can be reached externally as well via HAProxy. Running a ping from terminal on the firewall it returns the internal IP of the server so it should be connecting directly and not being proxied. On the Nextcloud server itself nothing seems to be logged, which is strange as well.


Any ideas? I did see another similar thread back in August with the same issue reported, but I'm not connecting via a reverse-proxy in my case as mentioned.
