Bitbucket-Jenkins webhook started to fail with 403 error reported by Squid

[gnumster]

I have had Webhooks setup in my Bitbucket account for a long time and they were successfully working fine... up until this morning.

This morning one of my Webhooks on one of my repositories started to report Error 403 with cut-down version of HTML response produced by Squid, or so it seems:

On my receiving end I have Jenkins hosted on AWS EC2 instance, which is opened to receive calls from anywhere. I have tested it by copy-paste the exact Webhook address line into my browser and firing the GET resuest to it. It works successfully - the build is triggered in Jenkins and everything works fine. All except Bitbucket Webhook, which worked yesterday and now it is not without me changing anything.

Any ideas on what might be a solution to this?

Hi! I've found this documentation about Running Jenkins behind Squid that might be useful. You can also try to find more resources at  Developer Help.

Kind regards,
