I’m working on getting a CI server setup for Yapp with Jenkins and the Jenkins github plugin. I ran into a puzzling roadblock that I will now blog for future me’s and you’s running into the issue.

The issue was that I was never seeing the github web hook request hitting my Jenkins server. I verified that I had setup the plugin correctly and disabled authentication for the web hook URL. After a bunch of experimentation and dead ends, my brother-in-law Micah suggested that perhaps Github is aborting when it sees the self-signed SSL certificate that I was using on the CI server. Sure enough, once I replaced the self-signed cert with a commercial cert from a recognized CA, everything started working perfectly.
