2016 Samsung TV Plex client just stopped working
3-4 month old Samsung KS8000 "Smart" TV, with Plex client built in, works mostly OK, bit kludgy in places but generally better then the basic Samsung DLNA client, prettier pictures!
Anyway, it just stopped working. No idea why. Open the client in the usual way & it tells me it can't connect to the server & now I don't have it I'm actually quite lost without it!
There's a primary & a backup Plex server, on same subnet, used to work OK with DHCP, tried static & didn't fix it.
Tried the "power TV off for 10 minutes" fix (basic heldesk 101) no fix. Removed all settings, re-entered, no fix. Rebooted servers, no fix.
Tizen 2.40 (apparently latest)
Plex client 3.0.11 (3.1.0) (no obvious update mechanism)
Plex servers 0.9.12.19 & 0.9.9.7 both worked well, previously, and still do with LG "smart" TV.
Got a full tcpdump from the primary server, attached, seems to show a successful initial contact, HTTP get, response = OK, then some no-ops & then 3-way Fin-Ack close, all quite sensible, no obvious errors, no firewalls, no clues.
Checked tcpdump on secondary server = identical. So clearly it's a Samsung bug, questions are:
Why did it suddenly stop?
How can I get it to start again?!
Any suggestions welcome, thanks in advance.
