Audirvana doesn't find music system/Upnp

Hello!
It takes a long time, up to an hour, for Audirvana to find my Linn music system. It seems to find other devices quite easy. Finding the Linn system works perfectly with my Linn app.
Is there some setting I should change? Debug info:

Audirvana Studio 2.11.0 (21100)
Windows 11 (26100) x86_64 with 8GB physical RAM

Hi @mjotor,

Can you go into the Audirvāna settings and in the My Account section? You will see a ‘Start Log Session’ button; click on it and reproduce your issue. After you reproduce it, click 'Stop Log Session’ and send me the audirvana_studio.log file you can find by clicking the 'Open Log Folder’ button at [email protected]

I have the same issue with my Linn Selekt. I need to reboot the Linn for it to be discovered. Both boxes are connected to the same unmanaged network switch.

I have these UPnP errors in the log:
[error]: UPnP select device: can’t find the device Linn Products Ltd Selekt DSM Edition with UID: uuid:4c494e4e-0026-0f22-7cc1-016177450171
