The remote server returned an error: (503) Server Unavailable.

The issue here is that while the application server is running, the Ideagen Internal Audit (Aura) service itself is not available.  This is usually caused by the application pool that runs the service being stopped.

To fix:

• Open IIS Manager
• Locate the Ideagen Internal Audit (Aura) folder, and then the Service application within it
• Open Basic Settings to verify the name of the application pool that is in use
• In the Application Pools section, locate the correct app pool and click Start
• Try launching Ideagen Internal Audit (Aura) again

If the same error occurs again, then the application pool is stopping when the Ideagen Internal Audit (Aura) service initialises.  This is normally caused by the password of the Windows user account specified for the application pool Identity having changed, or some other account-related issue.

More detail will be available in Windows Event Viewer (e.g. an Event ID 4625 showing a login failure for that Windows user account).  It will be necessary to fix this account-related issue before Ideagen Internal Audit (Aura) can start again (e.g. by resetting the Windows account password for the application pool’s Identity).
