have an iMac that remote access goes on and off



Imac, remote access sometimes works sometimes not, what are the appropriate settings for a Mac running high Sierra so that my iOS devices can see it.


Make sure you have port forwarded the port numbers in your router and in Plex make sure you select manually set, enter the same external port number, retry, then exit totally out of Plex and I mean totally even where the little Plex logo arrow is on the top menu, right click on that and exit, then relaunch Plex, should work now.
