Not available outside your network

Plex Media Server Remote Access
1

Server Version#: Version 1.42.2.10156
Player Version#:Version 4.147.1

I have been getting this for over a year and Ive had enough now.

Nokia Beacon G6 Router UPnP is enabled.

Server is Mac Mini M2 connected to a USB HDD enclosure of multiple drives. (Been setup like that for years).
Port forwarding has also been setup. Server has a static IP of 192.168.1.93. External & Internal port set as 32400. Protocol set as TCP & UDP.

I have enabled both “Manually specify public port” as 32400 and disabled it too to see if that sorts it.

Connection is not double NAT, 1gb Fibre connection.

All Plex works fine on the home network. Only when I go out… Sometimes it works, then drops. So it is working on occcasion. But takes me 5 mins to get a connection, then either drops or keeps restarting the show. This morning it connected, played 5 mins of 1 TV show, then came back with the error “No Libraries” (iPhone 16 Pro).
And on the Remote Access tab in Plex for Web, it flips between green “Fully accessible outside your network” and red “Not available outside your network” after about 2-5 seconds.

I am stumped/frustrated. Any help anyone?

What does https://canyouseeme.org/ show for your public port?

So apparently after a deep dive for a couple more hours and with the help of CHAT GPT, we have ISP-level CGNAT, so have to purchase a static IP from our ISP. Not sure why this is now the case, as been using Plex fine for a year on our fibre. So gonna see how much we now have to pay for this!
Thanks @dbirch for your input.

Keep in mind… technically, you only need a „publicly routable IPv4 address“ not a static one. Many ISPs will however only offer the static option (at a price).

Personally, I would not rely on an AI but call my ISP to confirm the approach and available options.

As for „why now“… that’s also a question for your ISP.

Thanks for the reply.
Unfortunately, Airband only offer DHCP (Airband owns and operates several blocks of public IPv4 addresses, which can be identified by their network ranges (prefixes) in BGP records.)

They’ve offered me a static IP for £5 a month, so looks like I will have to go down that route.
