I went to Boost in Podverse this morning and it failed.
I checked AlbyGo and it wouldn't connect which usually means my node is offline.
When I checked AlbyHub everything seemed ok so I unlink my account and it wouldnt reconnect

I mean what’s in the logs before those lines.
unlink should not be needed.
in such cases some connectivity issue is there. but I am not sure what caused it.
it could be that the hub could not connect to the relay for some reason.
This is what will fit on the screen. 
Any chance you could send the whole log file to Alby Support (support@getalby.com).
Do normal connections (e.g. Alby Go) work now?
the latest version v1.12.0 has an improvement there that better recovers from network connection issues to the relay.
not sure if this was the problem here, but maybe. let me know if it happens again
Start9 is at 1.10.4. I haven’t had this issue in months so I’ll keep you posted if it happens again.
