getting http 404 error (bitbucket-server)

[webdevops]

HTTP ERROR 404

Problem accessing /job/jenkins_URL/bitbucket-hook/. Reason:

    Not Found

I've followed the article in setting this up but still get the error.

I even have the bitbucket-hook/ at the end of my webhook URL. 

when I remove the bitbucket-hook/ from webhook URL i get a 200 but whenever I add bitbucket-hook/ at the end i get a 404 

my end goal is getting bitbucket to push master changes to jenkins, and for jenkins to build the code. 

any help would be appreciated.
