I mean, unattended upgrades has it’s own config file where you can specify when to schedule a reboot (when needed), which you’d usually do in off-hours like 2 AM your local time, so changing the Systemd unit activation time seems like the wrong fix.

Edit: Nevermind, your issue was that the daemons were being rebooted, not the whole system, if I understood that correctly

• Forgejo for private git repos, coz F GitHub (F as in paying respect obviously… :v)
• Portainer, though don’t use much as of late as I got used to the CLI
• qBittorrent for Linux ISOs. No, really, I use it to download Linux ISOs :v
• WireGuard, several instances, some for accessing specific services, one for accessing GeoIP blocked content when traveling
• Vaultwarden for managing passwords
• Home Assistant for managing a couple of sensors
• Nginx Proxy Manager for managing hosts

• Apache Subversion for private SVN repos
• A handmade C# service for storing some MQTT data into a database
• peaNUT a NUT dashboard for the UPS
• RustDesk for remote management of desktops

As for the hardware:

• A Raspberry pi 4 running Docker containers
• A Dell Wyse 5070 (16GB) running Proxmox with mainly Alpine Linux VMs

The way a reverse proxy works is to literally stand in the middle of a connection, so either side only sees them communicating with the proxy, oblivious to the actual endpoint. The only “solution” to this, though it’s more of a hack really, is to somehow send the original IP as additional data in a way that both sides agree on, e.g. the X-Forwarded-For header as others have mentioned, however, as I’ve said, both sides need to support and aggree with that, so you may have to find a setting/config to enable on the services behind the proxy. Think of it this way, if services blindly trusted that header and you weren’t using a reverse proxy, a bad actor could send a request to your service with that header included thereby spoofing their identity in your logs, therefore, this kind of thing is usually opt-in
