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.
- Sept 30, 2021 is when Let’s Encrypt’s old R3 certificate expired.
- ANY device which isn’t being updated ( Firmware updated ) is stuck.
- 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 ?
