Plex will not open ports after upgrade this morning

Plex Media Server Desktops & Laptops
1

This morning I installed plexmediaserver_1.13.5.5291-6fa5e50a8_amd64.deb and plex no longer opens 32400 or any other ports on my server. I don’t know exactly where to find the problem, but if I attempt to start Plex manually (i think i am not getting the config file loaded in) it starts like a new install.

My server is Debian GNU/Linux 9.5 (stretch) running in LXC.

Did the Debian in the LXC or the container’s Host OS update? (I suspect the host updated to impact the mapping like that)

3

The container did not, its possible Proxmox did, as I try and update it somewhat regularly.

I still have not done any updates to the container yet, but I have rebooted it since this problem arose.

I thought you might say ProxMox. :confused:
That’s one thing I know nothing about and can only point you back to the guide which was contributed about how to setup PMS to run in a Proxmox LXC. Double check / tweak perhaps?

5

I’m confused and a little baffled about the shear lack of no logs for Plex.

Is there a way to turn on debug log when i can’t get to the webpage?

Proxmox didn’t get a dist-upgrade, just packages. It could still be a LXC issue, but I would like to see some log to figure out where to go.

Something in the upgrade messed up permissions. It might be the plexupdate script, I’m not sure.

I changed all the permissions for /var/lib/plexmediaserver/* and boom webserver is back online.

wow, a dead-stop.

What does the os-log (journalctl) show (journalctl -xe | grep -i plex) ? That’s the only real diagnostic at this low a failure level

8

You have an external update script? MrWorf’s ?

journal showed nothing helpful

I’m using plexupdate from MrWolf, but it might be out of date.

I usually trigger it manually for fear of this stuff. :slight_smile:
