Server Version#: 1.13.7.5369
Player Version#: Plex Web (plex.tv/web)
I have Plex Server running on a Ubuntu 18.04.1 server via a dedication server provider. Enabling Remote Access fails each time I attempt to enable it.
https://<your-external-ip>:32400/web . Does the Plex web ui appear? Please click away the insecure warning or try http if you have not set the secure server settings to “Required”.
I will get back to you shortly. Everything on your side looks OK. Waiting for feedback. In the meantime please make sure IPv6 is disabled in the server settings. And please restart the Plex server with sudo systemctl restart plexmediaserver.
And a restart was also unsuccessful? Somehow, your server might not be correctly associated with your Plex account. There is an easy fix, but you will have to re-configure all your user shares. No meta data, no play state, … will get lost. Just the configuration of whom you share your server with.
In a nutshell:
(1) Web client server settings - General --> SIGN OUT next to “Signed in as”
(2) stop PMS: sudo systemctl stop plexmediaserver
(3) edit the Preferences.xml and remove the discussed entries in above document if they are still there, e.g. sudo vim /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Preferences.xml
(4) start PMS: sudo systemctl start plexmediaserver
(5) reclaim your PMS. The standard first time setup from “local network” . Just hit “Next” and everything should still be there.
Or for a less draconian measure, you can simply go to the settings in Tautulli and disable the “Monitor Plex Remote Access” option to work around this Plex bug.
There is a very small chance that you need to downgrade to 1.13.2. If you use the Ubuntu Plex repository the downgrade is easy: sudo apt-get install plexmediaserver=1.13.2.5154-fd05be322
Started from scratch with dpkg --purge plexmediaserver, reinstalling plex with apt install plexmediaserver=1.13.2.5154-fd05be322. Completed the initial setup from the “local network”. Remote Access is still not working.
