No loopback detected by Plex Media Server. Same as what i saw originally when you raised this topic
Without loopback the operation of the server cannot be guaranteed to work
Other clients may work because they may be asking for different size thumbs and the default prepared size may be good enough
But until there is a loopback IP address it is no point investigating any issue
Have a look at the linked topic i gave
