I did finally experience this error message when using my MacBook as an endpoint, but that is pretty rare. Also, I tend not to get this error once an album or radio has gotten going. The problem is starting that first track. All I want for Christmas is a properly functioning Roon. We’re having Verizon Fios internet installed this Wednesday. It will replace our current Comcast cable internet. I doubt it will impact this Roon issue but I’ll report back if it does.
