I've recently deployed a Jellyfin portainer stack (exactly as shown in this video) and afterwards shut down the server by typing "shutdown" in the CLI. Now I am presented with the Jellyfin setup after the server started up again: why did this happen; do you have any ideas on how to prevent this?
Also, additional question: I'm trying to set up Plex and Jellyfin servers since one device that I am planning to stream this media to doesn't have a working Jellyfin program for it, is that possible? I've set up a Plex Server the other day and it worked perfectly, but now that I've mounted the same shared folders to also be accessible for Jellyfin and set up Jellyfin yesterday, I am getting a weird error when starting Plex! It says, "Please check that the file exists and the necessary drive is mounted." I know for a fact that the drive was mounted before mounting it also to Jellyfin, could it be that a shared folder can only be mounted once? Although it's ab SMB share and open to anyone! I do not understand.
TL; DR: How to stop Jellyfin from resetting itself after a restart (and how to set up Plex and Jellyfin simultaneously)?
