I am setting up continuous integration using Jenkins and GitHub Enterprise.
So far I have been able to easily create Jenkins projects and run jobs regularly.
My next step is to configure Jenkins/GitHub so that each git push
to GitHub would trigger a Jenkins build job. I have set up the post-commit webhook on GitHub, and enabled the GitHub hook trigger for GITScm polling
checkbox in my Jenkins projects.
However, GitHub fails to connect to Jenkins.
Here is the log:
We couldn’t deliver this payload: failed to connect

What could be the problem?
Well the problem is exactly because github cannot access your internal network.
There's an article in Jenkins Community Blog where author suggests using smee (released under ISC License) for webhooks forwarding.
