No SPNs set for this account

Delegation Settings:

==================================================

The hostname you entered is : AppHost.qa.lan

SPNs needed for kerberos to work:

HTTP/AppHost.qa.lan

SPNs should be on account:qa\MyAppua

Required Delegation Settings

Delegation is not set.
We need to configure Either Constrained or Unconstrained Delegation.

Something is off and the error handler is not catching it. I ran as a domain admin and it did not matter.
