Nabu Casa: Unable to connect to Home Assistant

I am traveling and having a problem with my HA Green. In my Nabu Casa account I tried the Home Assistant Option > Log out from all devices.
Home Assistant now says it is unable to connect to Home Assistant.

My Nabu Casa account shows:
Remote UI > Your instance is not connected to Home Assistant Cloud
Remote address: Not available
Unable to connect to Home Assistant

Does anyone know how I can reestablish my HA connection while traveling?
