Apple Watch Remote does not go further as the 4 digits code

macOS 11.01, 

Music app 1.1.1.3

watchOS 7.1

if I try to connect the AppleWatch remote app to the iTunes library, get stuck.

At the situation you have to enter the 4 digits code in iTunes and confirm it with ok,

nothing happen on the Apple Watch. The 4 digits code stays active. When I close the code-page,

normally I could choose the available music library, but there is the starting page with "add device"

I tried to restart the iMac, the Apple Watch.

The remote app at the iPhone was working.

Thx
