Continued smol brain adventures in Docker

So I managed to get Docker set up (I think) with the help of a script called Deployrr, then used the linuxserver.io docker file thing.

The plex media server runs and I can see all my content in the web UI, however none of the plex apps can connect to it.

Can anyone help point me in the right direction to fix this without doxxing myself?

I'm really sorry but I actually don't know what half of these words mean.

This is why I feel like this container stuff is a really weird thing to make normie desktop users do. I'm out here like Hank Hill, "do I look like I know what a jpeg is?"

Plex was an easy MSI installer on Windows, I'm just so lost.

okay, first search “group/user id in docker settings” (it’s a variable that assigns as which type of user container masquerades as (admin/user/guest), if your system is restrictive enough, default numbers might lead it to run as guest without any rights to network access, those numbers are a string in environmental variables inside a docker and sometimes are missing from compose files, you’ll have to reintroduce them manually

second, your default assigned port in deployer or whatever might run into system restrictions of the host (another service running on that port or port range being blocked by firewall for some arcane reason), search for docker port problems or something, it’s usually what people will discuss. (although, if you see webui, that part is likely fine), *but checking with netstat (ipconfig? if you are on windows) still might show you something about the port (if it’s missing, that points to first problem being likely)

lastly, router maybe doing shenanigans on your server, specifically (you can try it out as entering not 127.0.0.1: port number, but as local server ip (192.something by default): port number on your server, which in theory will route request inside network once, although that maybe swapped silently, so not conclusive). can you ping your server (not plex, just server) from another device?

(Also, set it to bridge for a try)
