PMS suddenly shows issues with remote access 9/30/2021 10AM EST

So far I was able to manage my Plex server with the help of the documentation and other community posts, but the above issue with remote access gave me a bit of a headache.

Setup:

  1. PMS running in docker. Available for LAN on let’s say 192.168.0.100:32400
  2. Router has dynamic IP, forwarding incoming port 50000 to PMS.
  3. Custom URLs maintained: https://192.168.0.100:32400,https://plex.mydomain.com:50000
  4. Certificate properly set up in plex (Let’s Encrypt), full chain in pfx
  5. Wide variety of clients used: iOS, Mac, Web, Windows, LG TV
  6. Relay disabled, Remote access turned off, since I manage my own router to forward the requests and manage my own domain.

And it has been working fine for the last year, no hiccup at all. All clients were working correctly, without any problem.

On 1st October I noticed that the LG TV (43UM7100PLB, fw 05.10.25) client cannot connect. That is a remote client (parent’s TV :wink: ), not on the local network.
Found this forum and a lot of others mentioned that it might be connected to Let’s Encrypt’s change of cert.

I tried the followings:

  1. Signed out / signed in from client, reinstall the app
  2. Restarted the server
  3. Regenerated my certificate (for the domain)
  4. Removed cert-v2.p12 to make plex regenerate their own cert
  5. Enabled remote access
  6. Enabled and made insecure connections preferred (both client and server)
  7. Turned off auth

From this: Important information about Plex for smart TVs after September 30, 2021

I think the TV should be supported.

Turned on verbose on the server log, once I click on Try again on the TV, I only see the following:

What do I do wrong?
