[PROBLEM] Spotify does not see the device

[blino59]

Hi, my raspberry does not appear in spotify's list of connectable devices. I have a Spotify premium account, and 3 devices with the app installed (iphone, samsung tablet, PC). My raspberry is a PI3, the moode version is 7.3.0, dac HifiBerry and is connected by wifi to the home network. I checked ssid, ip address, password and i can access the web page of the device from each device. I activated Moode renderer in the SetupAudio section but none of my devices detects the raspberry among the connectable objects as opposed to the same devices.  What could be the cause of the problem?  Thank you
