I just created a new Plex Media Server as a Docker container using linuxserver/plex following this. Immediately after creating it, I tried to access the web interface at https://localhost:32400 and receive the following error:
Secure Connection Failed
An error occurred during a connection to localhost:32400. PR_END_OF_FILE_ERROR
I've recreated the container multiple times and still get the same result.
This is after trying to create one using plexinc/pms-docker. With the plexinc/pms-docker container, I was able to access the web interface but had to rebuild it and received the same "Secure Connection Failed" error when rebuilding it.
Any help is appreciated.
Are you using Firefox by any chance? If so, first try using something else. This is seemingly a Firefox only error and if you have to use Firefox make sure "Enable DNS over HTTP" is unticked in network settings. There is a whole list of other things to try too. Try here for instance: https://kinsta.com/knowledgebase/pr-end-of-file-error/
