I had a similar problem a while ago. Where I live we get many power outages. Every time I lost power I would get logged out of Alby hub. I would log back in, but the connection was lost. My node, on the other hand, was fine. Through trial and error, I deleted my stacker news and Alby Go connections in the Alby hub, then got the SN and Alby Go apps from the app store again, then started from scratch and generated new secrets. It worked, although a few times it took me hours to be able to re-establish a connection. Good luck
