Update with interesting test result:
We set up the cloud, on a network that IT admin said was open to the internet.
But neither my Mac nor the CC3 could reach the internet.
CC3 didn“t show up in the cloud, and ID number stayed orange in the CC3 html interface.
Interesting result: After running one playback for a few loops, CC3 froze and needed power cycle to wake up. This happened a few times.
When we turned off Send diagostics and deleted ID number, the freeze problem went away.
Now, idk what the network problem was. Possibly Mac address blocking?
