A User is constantly attempting to connect to the Automation Engine (AE), but is getting rejected, which negatively affects the System's performance. The Automation Engine, the GUI (AWI / Java User Interface) and other components like ARA suffer from this.
 

Investigation

Statistics of the faulty user are filled with a 'Rejected' status and "U00003210 Logon error : Access denied" error messages.

Cause:
Cause type:
Other
Root Cause: A user is being used in an external module and attempts to connect with invalid credentials.
Resolution:
Search for the usage of the user object. If not used in an object inside the Automation Engine or ARA - JOBS, JOBP, EVNT, you will need to search for connections from external applications attempting to connect via a CallAPI or a third-party application using the Java API.

Once the culprit has been found, ensure the user credentials it uses are valid.
