I had my IP address of UnRaid server change as I setup a new router, and messed up the original token ip address of my plex server, breaking plextraktsync plex token. Probably an issue for those not using static IP on their UnRaid server. This may or may not work, worth a try if it stops working. =p
go to your plextraktsync container data path in Terminal, ssh, putty, etc.
cd /mnt/user/appdata/plextraktsync
move original token json file for backup, before starting the plextraktsync container
mv .pytrakt.json .pytrakt.JSON
