Power Outage - Node 2 now has solid red light

Hello - I own a Node 2. We had a power outage and my Node now has a solid red light and the app says it cannot find the player. I unplugged the Node for about 15 minutes and that did not help. The Node is connected via Ethernet and the power cable is connected to an Audioquest Niagara 5000. Please tell me how to proceed. Thanks
