if i claim the server, it will break and only show “Not Authorized”. after removing the fields from Preferences.xml it will starts workking again.
it’s a fresh installation on proxmox LXC with the community scripts.
i access the server via localhost with tunnel and local ip. always the same.
Thanks . That excerpt is just enough.
-
Settings - Server - Network — Turn off the IPv6 support
(the ::ffff: , folled by IPv4, confirms you’re not using IPv6)
-
The ‘Unrecognized SNI’ means the client (plex/web or whatever) is using the old server certificate. Make that player/client restart and it’ll go away

Using Proxmox, Did you setup with TTECK ?
-
Are you comfortable enough with a little shell command line work ?
Hi!
- Already tried but no success
- The problem is with multiple Windows after some restarts
- Yes, it was a TTECK script
- Just give me everything you want.

I tried to set various settings via preferences.xml but sometimes it looks like it’s not doing the stuff after systemctl stop/start plexmediaserver
Do I have to reboot the hole lxc everytime?

Brace yourself! 
- Get UserCredentialReset from my Github
- Put it in the /config directory
- Untar it (tar xf … )
- Make UserCredentialReset.sh executable
- Run it (you’re already root)
- Get the token from https://plex.tv/claim
- COPY it
- PASTE into where UserCredentialReset is waiting for it.
- Hit enter.
If all successful, it responds with username and email.
Start PMS if it’s not already started for you
hi,
after this, i had the same Problem.
now, i have solved the issue. i deleted the plexonline variables from preferences.xml and delete Cache/, restart, ssh tunnel to the host, open the plex page with localhost. now i can access the server settings. claim server - ok this time. changed url to plex.tv. looks like i cann access the server. but it cannot activate remote access. i already set the manual port to 32400.
and when i want to play a movie i get “Error code: s1001 (Network)”. i never had this issues bevor in my installations…
this is a fresh install on a new server. should i start from scratch?
