Always get onboarding landing page when connecting to cloud HA

I have a running instance of HAOS on a Green.
I have a subscription to Nabu Casa and would love to connect from outside my home network.
Even if my instance is running since april, if I try to connect to HA from the link in Nabu Casa I always get the onboarding page, even if locally I see the normal view.

I tried to reset data of cloud from local HA instance, but nothing change.

Any suggestion?

File a ticket with Nabu Casa for this problem.
