PS4 Plex Stopped Working




So today my PS4 running plex has totally stopped working. First it wouldn't play anything in high quality and kept saying it had made an "indirect" connection with the server. Then after resetting everything on my network, it says my server in unreachable even though I can connect to my server on all my other devices, including a PS3.

I have been using plex on my PS4 for months with no issues in perfect quality, nothing has changed on my network and suddenly this morning it just won't connect at all. It suggests changing settings on the PS4 app, but the app is totally unresponsive. Can someone please suggest something. Its super frustrating!
