Cannot stream from macOS Big Sur / iOS 14.7

[Bouke]

I'm running the program on macOS 10.15 (iMac). I'm trying to stream from my MacBook Pro running 11.4 (Big Sur). It fails to connect. Firewall is off on the receiving end. Scanning over the Console.app output, it seems there's a pairing issue at fault.

Oh, curious. So just connecting? Or is there something in a play queue in the background somewhere?

Please pull the latest master - I attempted a fix there.
