Unable to restart plex after providing mount point

Upon installing plex I confirmed that it was working by going to the management page and indeed it was. I then stopped the service and provided plex with a mount point (source an NFS share and destination in iocage). Upon attempting to restart the plugin I repeatedly get this error.

Traceback (most recent call last):

I've searched and found no answers, restarted the server, uninstalled and reinstalled the plugin but to no avail.
