Plex won't start on fresh install

Hey, so I just installed quickbox on my new VPS and although everything went fine and plex installed without error as well, it won’t start. I only get the “service unavailable” page when trying to access it and systemctl status shows me this:

Apr 25 17:57:25 box systemd[1]: plexmediaserver.service: Unit entered failed state.
Apr 25 17:57:25 box systemd[1]: plexmediaserver.service: Failed with result 'exit-code'.
Apr 25 17:57:30 box systemd[1]: plexmediaserver.service: Service hold-off time over, scheduling restart.
Apr 25 17:57:30 box systemd[1]: Stopped Plex Media Server for Linux.
Apr 25 17:57:30 box systemd[1]: plexmediaserver.service: Start request repeated too quickly.
Apr 25 17:57:30 box systemd[1]: Failed to start Plex Media Server for Linux.

edit: i have seen this happen with this exact error message when /var/lib/plexmediaserver did not belong to the user plex, but this is not the case here.

Have you attempted to do box remove plex followed by box install plex. I just ran a few trials on a test VM and cannot reproduce an install error.

Additional to the above, what is the output of uname -a. This should not be an issue, I am simply curious.

uname -a
Linux box 4.4.0-72-generic #93-Ubuntu SMP Fri Mar 31 14:07:41 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

I just tried reinstalling from terminal, but it didn’t change anything
