LG tv - server not available

I’ve 3 LG tvs on my home network useing plex, 2 (which are only 4 years old) now display server unavailable - possibly after an upate. I’ve hard reset both, the router and the server PC and deleted and reinstalled teh app but with no change. The older TV which has the old plex app installed and all other devices (ipad, iphone etc) all work fine.

Does anyone haev a fix please

What version of PMS are you running? There are some threads of people here who ran into issues with the 1.43.3 version.

I’m running Version 1.43.3.10861

From what I’ve managed to read it all seesm to be to do with the sky router
