SWYH error -unable to connect

Hi all

I’m trying to play the audio from my Windows 10 HP Pavilion 23 desktop through to my Sonos Play1 speaker. Sonos is connect to my network via the Sonos wifi bridge.

In SWYH settings I have selected PM16/156
I’ve tried 8080 port and 5091 ports
I’ve copied the URL across to my SONOS controller app in radio stations
I’ve played something on my PC and then right clicked SWYH and I can see the SONOS speaker in the list, I’ve selected that speaker and hit play on the SONOS controller

I receive the error message - unable to connect

I’ve also checked via ipconfig that I have the right IP address for my PC

What is going wrong ! THanks
