Any help or ideas to try? Never had an issue with Plex like this before.

I have also been having this same issue with the Plex client for iPad. It has been randomly occurring multiple times during any movie or TV show I watch. My logs show the same error.

4

i have similar issue, i can connect to my Plex server via a browser, but using iOS or via my LG or Vizio tv it has the same can’t reach server issue

5

Same issue here trying to connect to my Synology. Has been working fine (mostly) for at least a year or so until a recent iOS app update. Now it can’t connect at all.
