I am trying to integrate jenkins and jira. I follow steps from this URL -> https://github.com/jenkinsci/jira-trigger-plugin

1. I follow each steps described in the URL
2. there is 1 thing I do not understand:
   “Set URL to: ${Jenkins URL}/jira-trigger-webhook-receiver/ e.g. http://localhost:8080/jenkins/jira-trigger-webhook-receiver/”
   my JIRA URL is : http://localhost:8080
   my JENKINS URL is : http://localhost:9090
   JIRA and JENKINS are running in the same server but using different port.
3. JIRA plugin in the JENKINS -> installed
   JENKIKN plugin in the JIRA -> installed
4. the JIRA logs are set to FINE

the conditions are:

1. whatever I update in the JIRA is not triggering the jenkins.
2. I am using JIRA server on prem.
3. I am using jenkins on prem

Please help….
