No remote access despite server state remote access is ok

Remote Access is for the Server.

The apps key off Plex.tv

If the app can reach the server on the local LAN – Remote Access isn’t used because the server is “Local”.

This whole Remote Access failing has always puzzled me.

I run a pfSense firewall. It is the DHCP / LAN domain manager.
I’ve never had any issue whatsoever with Remote Access not working and I have 3 servers always running with 2-3 more at any given time for testing.

When I was using DSL, with the ISP-provided modem, Remote Access NEVER worked no matter if I manually port forwarded or used Universal Plug & Pray.

Regarding this Secure Connection stuff.

  1. Sept 30, 2021 is when Let’s Encrypt’s old R3 certificate expired.
  2. ANY device which isn’t being updated ( Firmware updated ) is stuck.
  3. There are a lot of TV’s and other devices impacted by that. The announcement we made, as soon as we knew about it, is here:

What this means for those apps is just as written in the announcement about how to mitigate the core problem ( expired device certificate ).

Do you have the server requiring secure connection ?
Do you have the apps set to allow “insecure on LAN” ?

You know you can make exceptions for any LAN or WAN IP in Settings - Server - Network ?
