Environment

Dx NetOps Performance Management 23.3.13

Cause

incorrect config in SsoConfig

Resolution

Do the following to resolve

  1. Launch SsoConfig
  2. Under remote value change 
    • Change Web Service Scheme: http to https
    • Make sure 'local override' settings are blank

 

The URL will be built correctly for DM communication and the errors will go away
