Remote acces broken since last pms update

Plex Media Server Remote Access
1

Server Version#:1.43.0.10492
Player Version#:
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>

Hi, I did the most recent PMS update yesterday, since that the remote acces wont stay Green. When I enable remote acces its Green like 20 sec and return red and say its a double NAT problem. But I called Virgin and the IT said they dont use CGNAT. And I didnt have any problems before the update.

What I tried :

  • Port 32400 is well forwarder in modem interface
  • I dont use a router, only the Virgin modem
  • Another port didnt solve the problem
  • Disable Windows firewall changed nothing

Also the Plex relay dont work neither. When I try acces Plex outside my network I dont see the librairies.

Any help would be appreciate

Thx

I had the same problem to fix it

Ok go to settings

Remote access

Then tick manually specify public port

Enter 32400 and apply

This should now work its strange why you have to manually enter it when it uses the same port number

If you use a manual forward, you’ll need to tell Plex which port to use. Just because 32400 is the internally used port, doesn’t mean it applies to the outside.

check Plex Media Server.1.log which is located at C:\Users\%username%\AppData\Local\Plex Media Server\Logs for that string

172.104.218.101

that is PMS’s network address which is offline now.

Thank you all for your comments. I’m replying to everyone in this message.

I can confirm that in Plex I do indeed select the port manually, and that I open the port in my modem’s settings. Also, my firewall is always disabled to ensure that’s not the issue. I’ve tried several different ports, including 32400, 45000, 50000, etc. Each time it doesn’t work; the remote access appears for a few seconds and then turns red.

I’ve tried several different things: in Plex, I’ve tried IPv4 only, IPv6 only, and I’ve specified that Plex should only use my wifi2 network, but nothing works.

In my tests, I noticed that if UPnP is in my modem settings, the error I get in Plex is a Double NAT error. If I disable UPnP, the error in Plex becomes “Server not reachable outside your network”.

I checked the log file and I don’t see the IP address mentioned.

I had the same problem a few months ago. It turned out the issue was Tailscale on my PC, which seemed to be causing confusion in Plex, even though Tailscale wasn’t enabled. It was as if Plex couldn’t figure out how to access my network. Uninstalling Tailscale fixed the problem. Now the same issue has returned since the last Plex Media Server update, even though I no longer have any trace of Tailscale on my PC.

What I also don’t understand is why even Plex’s relay option isn’t working. Outside my network, I can’t even see the libraries.

Thx
