Volumio 3.703: Serviio server not detected


some time ago I reinstalled my pc where Serviio Server is running.
It “shares” both video and audio files and it is correctly detected by some devices on my local network (TV and mobile phones).
The only device that doesn’t detect it anymore is Volumio (Raspberry 3B+ + HifiBerry DAC Plus).
I tried to create a new source (Network Disk) but the scan of network disk fail so I had to set parameters manually and share the pc “audio” folder through Windows 11.
DLNA browser is active in Volumio.
Why Volumio doesn’t detect Serviio?
Thank you, regards.
