Bitbucket Server integration for Jenkins 403 no valid crumb

[Deleted user]

Plugin automatically creates a webhook with the wrong Jenkins URL.

It sends it to (jenkins)/bitbucket-server-webhook/trigger but there's no webpage there, does not resolve.

Tried setting it up manually with (jenkins)/bitbucket-scmsource-hook/notify per another community question around here, which gives me a 200 and is a resolvable page.

Bitbucket says that it went through, but there's still no build triggered. 

I can start the build on Jenkins side and it works.

I just want to setup the plugin, the video tutorial by Martin from Atlassian makes it seem so easy.

Great when you solve your own question. Had to make an application link between Jenkins and Stash per the plugin's page. Solved the problem.

Atlassian should update their video tutorial, it's misleading.
