TV and Server are in the same room. Tv is wireless connected, server by cable.
Funny, when I open media browser on the TV, I can easily navigate the server without any lag or issues, but as you know, I can’t have the Plex player features.
Just to add my two penneth. I’ve had exactly the same problem on my 2019 C9. Lots of helpful suggestions from other users/threads but nothing worked and zero input from Plex. I gave up in the end and bought an Shield TV (tube) and everything is ticketyboo.
I honestly don’t think Plex are going to sort this one out so you may want to go down the Shield or Fire Stick route.
Good luck!!
Just stated having the issue on my new LG TV. Open Plex it starts to load and then the screen flashes a few times and then I get Check Network Connection Error Code -337
This may be temporary blah blah blah
Everything else works. Sounding like if I want to use Plex on this POS TV I’ll have to buy a Roku
Same issue my new LG TV OLED55B9.
When i open Plex App i have this error:
Check Network Connection Error Code -337
On my 2 Samsung smart TVs all works well.
Please help
Today is the second day of Plex not working at all on my LGTV. Nothing I can do will get the app to work.
I have adjusted ALL suggested settings and nothing changes. At this point I’m just writing the LGTV app off as broken and will be using Plex on my XBOX until such a time I’m will to give the LG APP another shot.
gentlemen, error 337 is a problem of several months on LG TV! Plex doesn’t solve the problem and users get frustrated! The XPlay application works with the Plex server without any problems and without any changes to the settings, so this is clearly a problem with the Plex application on webOS.
