You may have some SSO issues when integrating, for example, OKTA with StatusGator. That might be a blank screen or throw an incorrect URL error.
Please try to disconnect and then reconnect OKTA SSO.
Adding the extra attribute, having it called simply `email` is what I'm proposing. For now, StatusGator doesn't use the NameID/ Subject from the SAMLResponse.
As simple as that may sound, please make sure you are still logged into StatusGator. Perhaps it is the persistent session on the StatusGator side that is helping you avoid the problem.
