Authentication problem when opening the Graphical Designer

You try to open theGraphical Designer but the action fails and you receive a message saying that the engine credentials are wrong, even though you entered the correct user name and password. This happens in a configuration with the Dynamic Workload Console connected to IBM Z Workload Scheduler connector on z/OS WebSphere Application Server Liberty Base.

The problem is due to the definition of the engine connection that contain the engine IP address instead of the hostname.

To solve the problem, open the Engine Connection Properties panel and replace the IP address with the hostname in the Connection Data section.
