FANTASTIC! Although the codes you sent me did not work, I looked for other sites with codes for the terminal window…
lsof -i 4tcp
The code above worked, it showed a list of all apps and the ports they use… Somehow, my torrent app switched on it’s own to port 32400, same as plex… So made the adjustment, launched plex and it worked… I am now rebuilding my database from back up, should be back to normal in 31 minutes… THANK YOU THANK YOU THANK YOU SO MUCH…
