Problem:
I have a very strange problem lately and I can’t find a solution. On some computers I cannot seem to acces my Plex web interface, I get stuck in the user selection screen.
My home PC and one laptop cannot log into plex via webinterface. I can use my credentials to log into plex just fine. However when I have to select my user, entering my PIN just does nothing. Also selecting the account of my child (no PIN) does nothing and the screen just stays there.
Another PC in my network can access it fine using the exact same login method. Also my Android phone can access the interface fine via both wifi and 4g.
I have setup a reverse proxy on my domain on both plex.domain.nl and domain.nl/plex. Both give the same result as accessing the server directly via :32400.
If I use app.plex.tv the login does seem to work and I at least get to access my settings.
My domain is running Organzr and using the Plex as OAuth to use the entire domain. The OAuth also fails and I am not able to use anything on the domain (from my normal PC).
And the weird part of it all is that this just randomly started a week or 2 back. Before that access was fine from all machines in my network.
Also running the Plex windows app
My setup
Server Version#: 1.19.4.2935
Running on Unraid (192.168.142.###) on linuxserver/plex docker in host mode, so direct access to all ports on the server.
Port 32400 is opened in my router and forwarded to this specific server. Remote connection is working fine according to Plex and this is confirmed by my family being able to use it from their homes as well.
Things i tried:
Removing the authorization from the devices using app.plex.tv and login back in. Only the initial login takes me past the user selection and into the services. Works fine on that run. When I force refresh the page it will end up on user selection and I am stuck again.
Adding 192.168.142.0/255.255.255.0 to List of IP addresses and networks that are allowed without auth. Works fine as long as I don’t want to do something with users or change user.
Adding “http://domain.nl:80,https://domain.nl:443,https://plex.domain.nl:443” to the Custom server access URLs also doesn’t seem to do anything for local of domain access.
What else could I try? Might there be something wrong with some credentials stuck somewhere in Plex?
