Recently, users have complained that Plex is not working on the Samsung Smart TV. Either they are unable to load videos or it is showing an error.

Let’s get started to explore why Plex is not working on your Samsung Smart TV and then I will discuss common Plex issues and how to fix them.

Why is Plex not working on my Samsung TV?

There are some other troubles like a black screen, subtitles not appearing, app crashes, and more.

These issues are occurring on older versions of smart TVs. Even Plex has announced through its forums and emails that they won’t be able to show content on older smart TVS. 

Plex Not working on Samsung TV

This is because the TV manufacturers are not cooperating with Plex. They are not bringing an update to their older TVs which led to the expiry of certificates. When a TV does not have an updated certificate, it does not offer secure connections for app servers.

The issue is common with Samsung, Vizio, Hisense, LG, and other Smart TVs.  

All this started back on 30th September. Let’s Encrypt offers free certificates to different websites which is like a safe guarantee card.

When a website has a Let’s Encrypt certificate, it is considered safe and valid. This non-profit free certificate was issued to a large number of people by the year 2018.

It caused safety problems. Let’s encrypt the DST Root CA X3 signature on the initial certificates. Later it started issuing ISRG Root X1 signatures and the previous cross signature expired. 

Now the new devices are updated with the latest signature but the older devices are still using the previous CA X3 signature. Hence, apps like Plex can not establish connections with older smart TVs. 

How do I get Plex to work on my Samsung TV?

Whether your Samsung TV is older or the latest, You can still be able to get Plex and enjoy its content on your TV. Here are some methods to fix it.

Your TV and the server should be connected to the same network. In case your remote is acting as a server. Then you can change the Plex settings.

  • Go to the Settings using your remote button.
