For the benefit of others that also run Plex Media Servers and also subscribe to AVG 2017 and are experience this same issue, I am going to uninstall and reinstall both AVG Tune Up and AVG Protection. The Plex Media Server running on my Drobo5N is still accessible internally and externally which definitely points to the AVG 2017 update being the culprit. Unless I disable AVG Protection (specifically the Firewall portion), even if PlexMediaServer.exe and PlexMediaServer.dll are added to the Exceptions list, the Plex Media Servers running on both of my PCs are not accessible.

Both of my Plex servers are not accessible externally or internal on my network since the AVG 2017 update took place.
