iOS 13.1, AppleMusic and WireGuard not working together

[Johannes Z. D. Mieth]

Dear all,

i am using WireGuard (1.0.6) on an iPhone 7 with iOS 13.1, the WireGuard endpoint is located at an Hetzner Cloud-Server (german hosting provider).
Since the update from iOS 12.4.1 to iOS 13.1 AppleMusic is no longer able to search for music while WireGuard is active.

Can anyone confirm this behaviour?
Is this specific to WireGuard or AppleMusic/iOS?
Unfortunately i am not able to check via a different endpoint as i only have this one on the Hetzner Cloud at the moment. Maybe Apple is blocking that network, but this would be unexpected and new to the current iOS version.

Sincerely,
	Johannes
