From screnshots it looks like you have two accounts: d0ena@ and d0enakalle@.

Log in to the other one and figrue which Account do you want to have connected to your Hub. You can easily "Unlink" and create connection anew.

Best! 

 No it's the same account. I've changed the address to d0ena@ to try connecting my 2nd Alby account and change the address over there to d0enakalle@. Both accounts showed the same error message. 

 Thanks anyway. I might also they reinstalling Alby Hub and take more time while going from step 1 to 5 of the Onboarding process..
