i doesn´t work if you not have root your TV 

I just switched the server to a different certificate provider than Lets encrypt in hopes that LG would eventually get this sorted out.

It should be very easy for LG to exchange the root certificates with an update. However, the question is whether this will happen....

Connections to older Plex servers still seem to work.
Also to those in the same network that are up to date but do not have their own certificates.

Whether this is really the problem is questionable.
However, SSL should be the most important thing these days and that must be running!
