Mezzmo not pickled up in TV Sources (over powerline)

Hi
I have Mezzmo 5.2 running on my windows PC. This connects into an ASUS router acting in AP mode then via Devolo powerline adapters to my primary router (A Virgin Media Hub 3.0).
My Samsung TV then connects also via the powerline

Mezzmo doesnt get picked up by the TV in Sources.

I've read through the article "cannot see Mezzmo server listed on your device" and followed the guide there. Mezzmo .exes and ports are open in Windows firewall on my PC. Everything is on the same subnet. The ASUS secondary router has DCHP, Firewall, IPTV etc disabled. I dont have any other media servers (except windows) installed.

Any ideas of what else I need to try?

Cheers

Can you please try disabling the Windows Firewall on the PC temporarily to see if the Samsung TV can see the Mezzmo server? The Mezzmo server sends out Notify messages when it starts so that devices on the network can try to connect to the server so if these are blocked then a device may not see the server. Devices can also send an M-Search message over the network which Mezzmo server will receive and respond to so if Mezzmo is unable to receive this due to the firewall or some other factor then the TV will not see the server.

That works. Once I disable the windows defender firewall, the TV can see Mezzmo.
However, I do have (multiple entries) in the firewall exceptions to let Mezzmo through.
I have: mezzmo.exe allowed for both public & Private
mezzmo media server
then the media server service is allowed through various ports on public & private and UDP & TCP but this seems a little random. Please could you tell me which ports should be allowed?

thanks

Can you please try re-enabling the firewall then go to 'Media Server Settings' in Mezzmo and if the button to configure the Windows Firewall is enabled try clicking on the button and this will configure the firewall with the correct settings. An issue with the configuring of the firewall was fixed in version 5.2.0.0 of Mezzmo so please check in Help->About to make sure you are running this version.
