Update: I figured it out. It works when running PMS inside docker, with bridge networking mode.
So it was a networking issue of some kind. Leaves me wondering why it didn’t work on a fresh install… But well, as long as it works now!
Hello,
I am trying to get Plex Media Server to run on my Raspberry Pi 3, running Raspbian Stretch.
I had it running before on Raspbian Jessie, however, recently I upgraded the OS to stretch and went with a clean start.
Then I tried to setup PMS, however, every time during the first time Setup, I get the following error:
A problem has been detected with a core component of Plex Media Server. Please visit the forums and provide your logs, as described here.
I have tried installing PMS via 2 different methods.
Via Package Manager and I also downloaded a Docker image and had that run. Both resulted in the same error.
Going through the logs (32.1 KB), I found that apparently PMS has, for whatever reason, problems accessing it’s own webserver via 127.0.0.1, I think? Trying to access http://127.0.0.1:32400/servers even resulted in error 401, unauthorized.
My first guess was that this could be related to my network configurations, since I am running my RP3 as a W-Lan Access Point for my home network, for which I have a network bridge set-up. So I flashed a fresh Raspbian Image, did the basic install so I had a completely fresh and updated Raspbian.
But, even then, I still got the same error.
At this point, I can’t figure out what causes this and any help would be really appreciated.
Thank you very much.
