Above is the error I was facing and when tried journalctl -u ncpa.service, getting the below error

I have updated the NCPA agent on the same server to ncpa-3.2.2-1 but still facing the same issue

Like the output says check /usr/local/ncpa/var/run/ncpa.pid.
Delete it id ncpa isn't running. Restart.

Hey , Thank you very much.

Sorry for not noticing such a entry in the output.

For windows, is there a any particular process to make NCPA up and running if it is being failed continuously. Your insights will help us
