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?

Scho docker by default runs on a separate network and resulting IP entirely unless you bind it to the host network or use a reverse proxy. The Plex docker also has a host network setup which I imagine handles this for you which you should try because it will act more like a normal local service. If you have a firewall that is catch all then it will block the docker IP which is something I bashed my head against for a while. If you wanna debug where your service is running there is netstat command eeeer. -tulpn I fink need to go get my laptop. Then you can list all the IPs and ports bound and find where Plex is running and work from there

sudo ss -tulpn

Or

sudo lsof -i -P -n
