Then you will love this documentary. It even mentions Germany a couple of times.

Rootless podman, PostgreSQL, redis, nextcloud, nginx, iptables in one…

I don’t know, I had Nextcloud for a year on a local network and I didn’t have to set an address. The bigger problem was that some applications do not accept self-signed SSL, so I had to change their code, and I don’t really know how to code for Android…

Maybe I should first ask the cellular provider for IPv6, because I misspoke; they support it but haven’t enabled it for me. If they provide it, then I won’t currently have a need for IPv4, but thank you for the advice.

Fair enough, personally I prefer to skip a few steps and then try to figure out what’s going on. It’s not the best approach, but I find it more interesting.

Gentoo is a bit more complex than arch so if installing Gentoo manually seems daunting I would recommend staying on arch.

Why? How will he progress if he don’t try harder things?

The problem was with DS-Lite tunneling, as some users mentioned, and it only works over IPv6. However, now I have another issue. My entire family has access through their ISPs, but my cellular data ISP does not support IPv6. Is there any workaround that doesn’t require me to look for a new ISP or asking for IPv4 address? 😀 By the way, thanks to everyone for the help!
