Plex can't find my server (on Synology) after updating to 1.15.1.710!

Clearly I’m not alone in running into strange issues with this…

Plex linux and asus rt-ac5300 remote access stopped working

I am running linux mint. I have an Asus Router RT-AC5300. At first I could not get remote access to work. I was able to create a port forward and remote access worked for a few days. I upgraded plex and now am not able to enable remote access. I have tried for days without success.
