Server Version#:
Player Version#: 2.013
Last weekend my Samsung TV UE40ES6100 stopped to recognize my server. I deleted the app and start a fresh instalation but also removed it from my account has a recognized device. Despite all of this it still freezes in the “enter code” menu and I can’t reconnect it again.
How can I fix it?
If I manually connect it to my server forces me not to use a user and password.
Thank you.
The solution is in the server to allow unauthenticated clients and just add to it the local IP address of the TV you want to use the app.
So all you have to do is:
In the server go to Settings/Network, show advanced options, and then specify the TV local IP address to connect to the server unauthenticated.
Go to the TV app and choose to manually specify the local address server IP in the TV app.
Done.
Everything is working again without updating the TV or buy extra add-ons for a perfectly working TV. 
Cheers
Samsung TV’s are not mentioned, but I am experiencing the same problem with my Samsung TV.
Samsung TVs are not supported anymore. Support officially stopped in 2019.
Check the solution…
Nice task for the Plex marketing employee to correct the website content. This Plex page refers to this Samsung page for a detailed definition of Tizen models. My TV is listed on that Samsung page.
I missed that there were tizen systems that were still supported. Learned something new. TY.
To be clear, v2.013 is an app developed by a 3rd party. Plex did officially support it, but not anymore. These TV do run Tizen but an older version. Samsung TVs with a newer Tizen version will run Plex’s v3.x app. Plex recently released a new v5.x app to replace v3. If you are running one of these, then your TV is still supported and should not have been affected. So if you ar ehaving trouble, please double check what version Plex app you are running first.
I’ve another Samsung smartTV - I guess from 2015’ish - and is working perfectly fine for me.
Anyway, I don’t care if the TV is old, I care that the app is working now as usual, so the problem is fixed.
It would be great if this could be updated in the Announcement & supported TV articles.
I’ll ask about it. But, technically, support for the v1 and v2 versions ended a long time ago so it wasn’t expected that listing these was needed.
My KS9000 is running Plex app 5.1, and cannot connect to my friends server, just comes up with server unavailable.
Nokia phone and Samsung tablet work fine.
I totally get that. However, no support hasn’t equalled doesn’t work until just recently. While you and I get what no support means, most other people don’t understand that. It could help save you from the scores of posts and emails that are showing up and will continue to do so for a good while longer. 
PMS version 0.9.8.0?
Thank you for the solution. I was not able to get my new Samsung TV to work, which is located in our vacation home. Can you post a screen shot where in the TV App you enter the server IP address? Thanks.
As you can see, this is the information that I’ve in another Samsung TV that is working fine.
In my TV when I get the menu to Connect to plex - as in the first picture - I press the red button on the remote.
Then it asks if I want to add manually the server. Then it automatically flows though the menus to show the settings to add the IP.
I have the same Problem, on my Samsung from 2015 ueH6400 the plex app 2.013 is working on my ueES8090 it can’t connect. Only via IP. The Problem is that without Account Connect, my Plex Lifetime Pass dosen’t work on my ES8090 that means i have no Trailers etc. Why does the same App works on one TV, but on the other it doesen’t? Could u please resupport the old tizen App?
