Hello, even if Plex now works on my Panasonic I decided to buy the Amazon fire tv stick mainly because Disney+ was not available on Panasonic APPs. Well, the Plex client on it is 10 times better, faster and the encoding is done by the stick (quad processor 8gb ram for…59 Euro), now 4K file HDR works perfectly. … my two cents.
Hi. I was having this problem as mentioned. Unfortunately whatever was done in the background did not work for me either. I have however discovered something that may help other users with this problem but a pain as you have to do it every time.
When I get the Plex server is not reachable message there is an option to
Open Settings.
Scroll down to Manual servers and enter the Plex Server IP Address and OK out.
Close settings box.
DO NOT RETRY IT WILL FAIL
In the top left hand corner (For me anyway) the magnifying glass symbol (search) appeared.
I then selected this (you do not have to search for anything) and then moved over to top right hand corner and selected home.
This then bought up the Media and was able to play without problems.
Hope this may help others in the same boat and as previously mentioned you will have to do this every time as it doesn’t save.
Thanks
I’m having same issues, can someone help? 
Hi, I’m in SIngapore and having this problem too. I noticed that the issue could be that I am no longer signed, the top right user pic is not showing my avatar. When I click on the the “Sign in” button nothing much happens, just goes back to the PLEX banner and then returns to the same screen. Settings doesn’t have an option to sign in. I tried uninstalling and reinstalling the app but still no working option to sign in.
Same for me in Italy, Panasonic AS650…
From what I understand from above messages no chances to have it working again 
I should imagine it would be a simple fix to correctly enable the “Sign In” button, so I can sign in
@BigWheel Do we have any update on this? some have said its fixed, but many its still not working
It won’t work on tvs that don’t support tls 1.2. Though we changed what we could to get some folks running. there is nothing else that is going to be done on our side because we are not renabeling outdated security
@BigWheel I take it that means those that pay for Plex Pass should cancel?

@shaiboyuk1 Depends what features of plex pass you are using.
PlexPass never enabled access via the Panasonic App so if you were paying for it to get that then you were paying unnecessarily anyway.
For the love of everything that is good… why oh why oh why are you screwing with stuff that is entirely within our own network?
My tv, my server, my apps and content are inside my network. It should not require any security or changes to the existing security to allow something that worked a month ago to continue working today, it should still work in 10 years time for goodness sake.
They are not. You connect to THEIR services when you load the Panasonic app. They don’t feel that THEIR services should use an ineffective security method so they forced THEIR services to use a better one. Unfortunately YOUR TV cant handle that.
The solution. Upgrade YOUR method of watching TV to something that is compatible with THEIR back end services.

That’s the thing isn’t it, there’s no reason for the tv to connect anywhere but the internally hosted server, if that’s what the end user wants from the software.
Then just use the built in web browser on your TV and connect it to your server.
Just because you don’t know how web apps on TVs work doesn’t mean anyone is doing it wrong.
I now can’t access plex on my two Samsung TV’s Works on tablets and phone, seems Plex don’t want us viewing from TVs…
My guess, they where older Sammies?
If so, please state TV model and Plex Client used, and when said, then do note the following:
- Due to the world been a sometime nasty place, where hackers etc. lives, Plex has to upgrade their WebSite security in order to protect us all!
- As such, Plex upgraded their websites to use newer encryption, as well as chipers. (Ref: Plex support is ending 2020-09-30 on older smart TV devices)
- And if they didn’t do that, everybody would be in the risk of been comprimised
- This sadly means, that if a TV vendor hasn’t updated their OS to support newer encryption or chipers, the TV can’t connect to a WebSite, that has (And should have) their security updated
- Sadly, I have +3 Sammies E-Series (2012) that by Sammy is deemed EOL, so they have not been updated by Samsung.
- This could be both due to a Samsung policy, or due to HW in the TV can’t handle it, so I’ll refrain from judging here
For Samsung E-Series, their supported Chipers, are sadly more or less unsecure

So in short…
A Smart-TV is a computer, and my TV from 2012 is a very old computer, so I sadly have to figure out new ways here, since I naturally doesn’t expect Plex to downgrade => compromise us all
So I’ll be looking for a thing like a shield, Apple-TV or a Chromecast
Hey guys
i am based in new zealand and found that i had the same issue, i have been in touch with the nz product manager and can confirm that nz are not losing panasonic tvs only australia
he provided me an interesting work around which worked for me and that is to change the date/time setting on the tv to manual and enter todays date, this got me up and running i am unsure of others
i have questioned for NZ as support will still be provided when i can expect a plex update roll out, they will get back to me, they also confirmed disney+ has been delayed due to covid
Thanks
Hi mikenz1983,
Thank you for contacting Panasonic and letting us know the information they provided.
Unfortunately this workaround doesn’t work for me.
Myself and many other Panasonic TV owners would be interested to hear any news on this if you hear back from Panasonic.
This is so disappointing from Plex.
I have recommended Plex to many who have used and loved the Panasonic Smart TV app which worked perfectly for their needs.
Some of whom have purchased Plex subscriptions as a result.
Sadly they can no longer enjoy Plex in this convenient way.
During a global pandemic many can not afford to purchase extra devices such as an Apple TV to be able to use Plex again.
Plex was one of the few constants that many relied on for their entertainment during these times and that has now been taken away.
Please Plex, do the right thing by your loyal users and re-enable support for Panasonic and other Smart TV players.
You cant, Plex have already stated that the Panasonic Plex app will not be updated and it will receive no support from them.
I think hiteck summed up how many users feel in this post:
Please smash the like button on common-sense posts and suggestions like this, so that Plex understand how many loyal users they are disappointing with their current direction.
