Resolve error "service terminated with service-specific error incorrect function" while starting Quadstone portal websrver qp2.2A in Portrait SSA

Issue

Customer was not able to start the Quadstone portal web server qp2.2A in Portrait SSA after updating the certificate.

While trying to start it, he was getting Error "service terminated with service-specific error incorrect function".

Please see attachment - Error.png.

Cause

Service was not able to come up because certificate.crt referred in the httpd config file does not exist.

Resolution

UPDATED: November 3, 2017
Please refer to Root-cause.png.

When we changed the config file to server.crt (which does exists) we were able to start all the Quadstone services and see the login page of SSA.
