It might be that that Plex can throw this exception for many reasons. So maybe the Plex devs are glossing over this thread because they think we are reporting many different unconnected bugs.

I also am always in offline mode (Plex HTPC should automatically reconnect after resume from sleep / internet availability)

And also habitually manually reconnect.
