I cannot connect my Nas server to Ple

I cannot connect my Nas to Plex when I click the IP address on docker linuxserver it’s going to the web/index.htm but the server is not showing up

Are linuxserver_plex-1 and WIN-BSNPG6GPR2H the same Plex machine?
How’s the network of your container configured (e.g. as host network, bridge…)?

no that’s old one that i am not uesng anymore

Your Docker server is not connected to your plex account.
So that is the first thing you need to fix.

how to do that

First thing, do yourself a favor and change the network of the Plex server container to use “host network”. Once you’ve done that and restarted the server:

I’m no expert for Linux, but this should get you going: Unable to access server after password reset - #99 by FordGuy61

Official documentation of the Plex docker: pms-docker/README.md at master · plexinc/pms-docker · GitHub

man this is so complicated I have no idea how to do this

Then maybe Linux/Docker is just not for you?
