Jira Intigration fails

Hi All,

I am trying to integrate Gitlab.com with our Jira application, while doing this we are getting error which is “test failed. execution expired”.

The gitlab.com will connect to our internal environment using a whitelisted IP, We have the IP whitelisted still gitlab.com is not able to connect, do we have to perform any other configuration so that gitlab.com can talk to our internal servers.
