Cause

- certificate.pem file

Environment

Release : UIM 9.0.2 or higher

Component : UIM - UMP/OC

Resolution

Recopy the actual in-place certificate.pem file to the UMP/OC Robot from the Primary Hub. For example:

On a Windows OS at:

   C:\Program Files (x86)\Nimsoft\security\certificate.pem

On Linux/UNIX OS at:

   /opt/CA/nimsoft/security/certificate.pem

and then also double check the reference in the UMP/Operator Console machine-> robot.cfg.

For example, here is a partial extract of a portion of a robot.cfg showing the cryptkey (certificate.pem file) location entry:

Post replacing / overwriting the existing in-place certificate.pem file, UMP/OC wasp should be able to be started and work as expected.

- Deactivate wasp

  Wait until the port and PID disappear

- Activate wasp
