So... I've been offline for a couple of weeks. What did I miss?

Long story short, I broke my setup by factory-resetting my router (necessary due to bad ISP), which resulted in it going out of bridge mode and thus firewalling all trafic. Silly me forgot that it would do that, so I was unable to fix it until inspiration struck me right now. 😭

On the other hand I replaced my Nginx reverse-proxy with https://caddyserver.com, and that is sweeet. 🤩
