Need help with Denon AVR S750H Heos

[Bocat]

I recently purchased my first Denon, after being a Pioneer guy my whole adult life. I love it. One question, I have Heos set up. Yesterday, I went to use Heos, and the on screen display says no network connection, please check your network connection and try again. Now, I know for sure that I am connected to my network via ethernet. As a matter of fact, when I go to network, it says connected. When I go to the Heos app on my phone, it works just fine. We did lose power for a few minutes yesterday morning, not sure if that has any bearing on this, though it would seem to.
Any suggestions on how to solve this dilemma? Seems like I need to reset something, just not sure what.

The same thing happens to me. HEOS playing, receiver says, “no network connection”

Never mind, I figured it out on my own, I needed to hold down ZONE2 ON/OFF and ZONE2 SOURCE at the same time for at least 3 seconds. It then resets the network connection. And it worked.
