Honestly, i don't think anyone knows what is happening what is going on inside the docker-compose files i set my instance up with 0.17.4/prod file with some tweaks.

Gotta stick with the 1st rule of engineering: "If it works, do not touch it"

Also i don't know if my full works, cause i can federate with everybody except lemmy.ml (which i guess is a error on their end?)

Yea, its sometimes annoying when you have to manage 2 firewalls (still to this day i find the Oracle interface too messy), but it makes it secure

I do have this setup, but i don't think that npm can reach the HA, i have tried through direct IP and 127.0.0.1 and none of them seemed to work.
