Couldn't connect ATEM PS 4K with HyperDeck Studio mini ?

Hello Forum Team

My Name is Alex King
I bought a BlackMagic Design Produktion Studio 4K and a HyperDeck Studio Mini.

My Problem is, that I CAN NOT connect them via the “Remote Control on” feature on the HyperDeck Studio mini to the ATEM?
I could not see the HyperDeck Studio mini on the ATEM Production Studio 4K to remote contol them via the ATEM Software?
On the ATEM Software there only stands, “Please Connect a HyperDeck Studio” !!!

Both have the latest Firmware and connected via USB, LAN and SDI and are working perfectly for their selves alone!
What do I make wrong?

Kindly regards from Austria

Problem is solved, thank you!
