When trying to open a project using Open Workbench (OWB) or Microsoft Project (MSP) from Clarity PPM, one or both of the following pWbench messages appear:

 

• A server error occurred during login: - Server returned HTTP response code  401 for URL: <https Clarity URL>
• Unable to connect to Host. You may be trying to connect to a host that is currently offline of does not exist. 
• Unknown Login error
  
  

Environment

Release : All supported releases

Cause

This can be due to the SchedulerURL in the properties.xml (CSA/NSA) being missing or incorrect. If using https, this should be updated to include the https URL.

Resolution

Update the Scheduler URL in CSA/NSA with the https URL (Example: https://<clarity_host>:443) then restart the app services.
