I created a redshift cluster and populated some sample tables inside. All works fine. I switched to another cluster (empty) and tried to switch back to the first one.
I was asked to enter the password which I am sure it is correct because I just logged 30 mins ago. But this time, it says "Failed to connect to query service." When I click on "Connect with temporary password". I got exactly the same message. enter image description here
I am very puzzled, as what could have caused that? And I can't find this exact error message anywhere.
Any idea? Thank you very much! Ming
