post-build-status-update not working with nodejs/node

[maclover7]

Original issue: nodejs/node#17358

Culprit looks like it's #985, but it's kind of confusing. It seems like the IP addresses are setup correctly, but getting this error in the github-bot logs:

16:19:09.613  WARN bot: Ignoring, not allowed to push Jenkins updates (req_id=22f36a15-bbd7-40b7-b0e1-75306c0d81e7, ip=::ffff:147.75.73.189)

Maybe it's the "::ffff:" that's throwing things off?

Is happening with the other server as well: 16:19:08.250 WARN bot: Ignoring, not allowed to push Jenkins updates (req_id=7ada38f2-de42-47b9-8746-e582ad53a907, ip=::ffff:147.75.69.113)

This seems to be working again, closing.
