Plex server unreachable

Hi all,

After a new Virgin install my Plex server is no longer reachable from any other device (inc. the server itself, a laptop) on the LAN or wifi, even though everything is on the same subnet and the server itself works perfectly.

Is there a way to change the 32400 port as I think the Virgin hub is dropping it?

Setup

  • Plex Media Server (latest 2025 version, clean reinstall, database wiped) on Windows 11 laptop @ 192.168.0.217 (Wi-Fi)

  • Clients: iPad, Android phone, smart TVs – all get 192.168.0.x addresses from the same Virgin Hub

  • Media on My Book Live (192.168.0.248 – reachable via SMB from Windows) I KNOW, THIS IS OLD BUT IT (DID) WORK

  • netstat on server shows:

    text

    TCP    0.0.0.0:32400     0.0.0.0:0    LISTENING
    TCP    [::]:32400        [::]:0       LISTENING
    
  • http://127.0.0.1:32400/web and http://192.168.0.217:32400/web work perfectly on the laptop itself

  • From any other device on the same LAN (including when laptop is on Ethernet) → http://192.168.0.217:32400 times out completely

  • Windows Firewall fully disabled + Norton disabled = no change

  • Secure connections = Preferred, LAN networks contains 192.168.0.0/24, “allowed without auth” contains 192.168.0.0/24

  • No client isolation / AP isolation visible in Hub settings (Virgin Hub UI is locked down as usual)

I’ve had Virgin before and Plex worked fine – something in the new Hub firmware seems to be silently dropping LAN-to-LAN traffic on port 32400 (or all non-80/443 ports). I’m not buying another router just for this.

Been through problem solving with Grok but here I am!

Thanks!

Fixed this…

Made the server a Static IP, reserved the IP, port forwarded the IP and created an exception in the firewall…done!

Oh and don’t use Grok to problem solve, it overthinks it…
