Sorry, I can’t follow the point you’re making. What’s “the great Con Switch”?
Remote access involves a lot of systems – your PMS install, the host OS running your PMS, your home network architecture/structure, your router. Last not least, many aspects are under the control of your ISP.
While you might not want to need to know how it works… you’ll need to dig a bit deeper. Plex simply doesn’t have the full picture of your individual remote access setup and situation.
In case you’re banging your head against the wall as to why your server seems to be working fine and you can access it remotely, but it still gives you a “Not available outside your network” error within 60 seconds of enabling: Plex’s (the company) heartbeat servers are located in Ireland. If you have GeoIP/country blocking enabled on your firewall, it can cause this hiccup.
What makes you think that nothing changed (except for Plex)? You usually won’t be informed by your ISP about all the technical changes they do in their backend — based on your exact argument… they consider their customers don’t want to understand/know how it works.
Troubleshooting a troublesome remote access setup can be painful when it comes to the stuff outside your control. And I’m sorry to say, it’ll usually require at least a little of dealing with the „how it works“ (or in that case, how it doesn’t work).
The guide above is a starting point with checks that can help to pin things down and to get to the culprit in your individual setup.
I’ve moved your posts into an own thread to attempt figuring this out.
It’s a bit hard. I understand your frustration, but between those posts you’ve provided very little information on your setup and what you already tried to fix this issue.
To further troubleshoot, it’ll help if you provide details on the output of the troubleshooting steps… not so much the outcome alone (I understand it’s not working). The outputs give clues on where to find what’s going wrong.
For starters…
Can you open canyouseeme.org from within your home network and test if the site can see your Plex remote access port?
Also, does the public IP listed for your request match that listed as public IP in the Plex remote access settings?
Bonus: if you have access to your router… do the public IPs listed on canyouseeme.org and the Plex remote access settings match the router’s WAN IP?
If you don’t mind, could you post the first and second number of those public IP addresses (the IP consists of four sets of numbers, e.g. 10.125.5.52 — in that case I’ll only care about the 10.125, you don’t have to expose the full details).
