Audirvana remote not connecting

Hi, I have installed the last update available on Audirvana studio (2.2.3) and now the remote app is not able to connect anymore (I never esperienced any problem with the previous versions). The error message is: “Unable to connect to the device. Please use the same wifi network on both devices to make the connection possible”…but both are working on the same network.

Let me know for any suggetion to fix the problem.

Many thanks
