Rachio valve hub cycling through all colors after offline over winter

After bring offline for the winter, upon reconnecting power, my Hub 101 is cycling through all colors (green, blue, yellow, red, white purple).
I can see traffic from the device on my firewall and obviously it’s online but not connecting in the app. What’s the next troubleshooting step? -Nothing has changed on my side since shutting it off for the winter.
TIA!
