Cause

The firewall on the AWS EC2 environment blocked [redirect_uri=http://127.0.0.1] which was included in the URL sent from Tableau Desktop to complete LBLM.

Additional Information

When signing into Tableau Server or making LBLM activation, the below behavior was found.
1. With an external browser, [http://127.0.0.1] is included in the sign-in URL in the browser.
2. With an embedded browser, [http://127.0.0.1] is not included in the sign-in request.
