Plex suddenly shows server offline on Smart TVs, fine on Mac/Android

Server Version#: 1.20.4.3517
This is quite bizarre. Plex server has been happily working for years with all my devices (stopped for a bit on the Panasonic recently, but it was fixed). Yesterday, I installed a vpn client to do some work on the Mac Pro server machine, briefly switched to DHCP from static IP, then put it back on static. This may or may not be related - I am just documenting everything remotely related I did, but, in any case, later in the day I go to my Samsung TV (v 2.0.13), and it shows the Mac Pro server is offline. Weird. I go to my Panasonic TV, Plex loads, I click to watch and gets stuck on three dots, after that it claims server unreachable, showing the correct IP. My Android phone Plex client works fine. My Macbook Plex client works fine. I tried:
-Telnet to the server IP/port from other devices on the network: server replies.
-Installing an update to the Plex server (latest), restarting.
-Logging out of Smart TV Apps, then signing in again. The signing works, but they don’t see the server. With the server console open I do not see any requests from the Smart TV clients.
-Uninstalling/reinstalling apps.
-Checking server settings - I did not change anything that day, secure connection is “preferred” etc standard settings.
-Manual IP on Pana client.
I don’t understand, I only have a single subnet, the TV apps find the account fine, get the correct IP, but then nothing, without me having changed something else. Any ideas about what I am missing or what else I could do to troubleshoot?

Sadly no longer supported

WorkAround:

But on September 30th my Panasonic app did stop (in a different way), and there were threads here with many people reporting it, so it was temporarily fixed for us and the Samsung was fine (the announcement said v1.x apps would stop, I have v2.x). So they were working until at least this Wednesday (November 11), they stopped yesterday. I checked to see if there were new threads with people claiming the apps stopped, and there were no complaints like a month or so ago. So it seems it is a different issue? Did something change yesterday on the Plex side?

Nope, Issue as I said.

Plex have lost a lot of fans with this move.
Please vote for Plex to support the Panasonic Smart TV app on all devices:

People was screaming for better security, so I humbly disagree

Hi Dane22,
Sure some people were.
However you need only look in the forums over the past few months at the endless complaints and frustrations from those with slightly older ‘smart’ tvs who have been left in the dark.
Many can’t afford to buy yet another new tv or another device like an Apple TV to be able to do what they could already do with their smart TV.

I don’t understand why I would need better security for my internal network, streaming video from one computer to another, but I can’t personally complain as I don’t have a paid subscription - free software can stop working, which is a bummer especially when I consider it kind of a silly decision, but that’s as far as I would go.
The Samsung TV is older, but it is a 60" Full HD Plasma, which is exactly what I want quality wise, I don’t like LCD/LED quality, so I have to wait for more OLED panels. The Panasonic is a bit unlucky, it is a quite new 50" 4k for the bedroom that seemed to have a Plex app. Anyway, I’ll find a way to still use Plex. The Fire stick (non-4k model) is out though, tried that and it is horrible playback quality even for h264 videos.

A player authenticates towards plex.tv, so without increased security, everybody is in danger!

The 3.Party Orca Client worked on -2015 TV’s only, so as a bare minimum, your TV is at least 5 years old. Granted that might not be “old” for a TV, but…

The Smart-TV part of it is a computer, and a 5 years old computer is IMHO an old computer.

When said, you should instead complain towards Samsung, since they are the ones that stopped FW upgrades providing support for newer security protocols and chipers

I said I won’t complain about a free app, but I will respond to the comment that is dodging the issue via FUD. The old app DOES connect successfully to plex.tv and does get the registered internal IP of my plex server. It then fails to connect to the internal server - the internal connection is the problem, which I don’t care if it is secure. I mean, theoretically not even going to plex.tv would be needed for a local network system (like Plex used to work years ago), but obviously the plex.tv thing adds more possibilities which apart from giving people more options, also drive more revenue, something I can respect.
If it wasn’t clear, I respect a free app not trying too hard to support a few uncommon use cases, I just responded because I get annoyed by people using “security” as a trump card for everything, spreading FUD (“everybody is in danger!”). No, google, plain html sites don’t need to be demoted in the search results if they refuse to go through the trouble (and/or expense) to switch to https, no bank I will not name, I don’t need to change my password every single month (most of your users will be writing on post-its instead). And I won’t even go into the Patriot Act! :smiley:

Since you still haven’t mentioned the year/model of your device, I’m kinda fighting blindfolded here!

If you reinstall the app, and it afterwards will show you a pin-code to register, then yes, the Samsung Firmware does support TLS 1.2 and the newer chipers, and as such, you have another issue of some kind, that could be related to PMS and updating info to plex.tv

If so, try on the PMS and disable remote access, followed after 1 min by re-enabling it again.
Doing so would update the info on plex.tv.

If above doesn’t help, then debug logs from PMS would be helpful
