Hey guys,

Looking for some assistance with this, keep getting this error when trying to update the commit status on a PR:

However when I run a commit status from POSTMAN with the exact same urls and so on it works:

{
  "url": "http://policestate/api/v3/repos/operationalplatform/ruby-workbench/statuses/e77d34b0cb8e79456a7df6c99e879dfec98e9082",

    "received_events_url": "http://policestate/api/v3/users/callum/received_events",
    "type": "User",
    "site_admin": false
  }
}

Github Ent version: 284
GHPRB version: 1.33.4
Jenkins version: 2.7.4

Any assistance with regards to this issue would be greatly appreciated.

Turns out it was a DNS issue we were facing.

We were running Jenkins as a container in Openshift and had our github URL specified as a namespace which was causing a initial redirect.
