Could you post the output of ufw status verbose ?

A bit late, but keep in mind, TMDB is not FOSS and is owned and run by a private company.

Or look into FreeTube, it works really well on desktop

It’s a good bot ;-)

You could also look into OpenWrt and maybe get your device an open firmware. For a more advanced setup you can look into OPNsense, but you will probably need additional devices for WLAN, DECT, etc.

Depending on where you live, you should be aware of the fox tapeworm. It’s really, really nasty for humans and can be fatal.
