Describe the issue

After my upgrade to ROON ROCK 3.0 the server (NUC) startup fine. When I look at my iPhone (or other ROON cliënts) and I choose settings-audio I see al my playback devices. The issue is I can’t playback any music on any of those devices. I enable them, but no chance to play, the play button is grayed out. I did a reinstall, reset the network, routers, wifi, everything. No result.

Describe your network setup

I make use of the Dutch KPN router Experiabox with a set of Netgear Orbi 850 AP's. Roon Rock is installed on a Intel NUC.
