I guess your OPNSense rule from Edit3 is not working because the source is not your mailu instance, because connections are initiated from the outside and mailu only answers (TCP ACK). So you have asynchornous routing.

You may get this working if you set the "reply-to" option to the wg gateway on the firewall rule that allows VPS -> wg -> mailu traffic.

However there is a much cleaner solution using the PROXY protocol, which mailu seems to support: https://mailu.io/master/reverse.html

They are using traefik, but nginx also supports the PROXY protocol.

From your description I would gues that the affected trackers have some rate or connection limits, and your qbittorrent announces are exceeding them. try setting a higher announce interval, like 1+ hours

I'm surprised no one mentioned ansible yet. It's meant for this (and more).

By ssh keys I assume you're talking about authorized_keys, not private keys. I agree with other posters that private keys should not be synced, just generate new ones and add them to the relevant servers authorized_keys with ansible.

750gb upload, 5tb download per day. However this seems to be another limit, maybe file based max sharing or something.

guys are not downloading enough 😅
