Server Version#: Plex Media Server v1.27.0.5897-3940636f2 - Ubuntu PC x86_64 - build: linux-x86_64 debian Player Version#: Plex Web 4.76.1
Hello,
I had for some years Plex running with no issues on Debian 9 due to it going EOL now, I reinstalled the server with Ubuntu 20.04.4 LTS (Focal Fossa)
Installed the Plex server according to Installation | Plex Support
When opening http://<public-ip>:32400/web it does redirect to /web/index.html#!/setup/765b66c23ba8236200af99dc22c6969884184429 as expected but as soon as I login then it does go to /web/index.html#!/ and if I then go back to the setup URL I get the error You do not have access to this server.
