I am setting up a new workflow and ran into something.  When I change the repository to private I get timeouts, changing it over to public it again and it can build.

Here it is as a public repo:

> git.exe fetch -no-tags --progress https://bitbucket.org/interplx/accesslayer.git +refs/heads/TD-47-branch-support-for-jenkinsfile:refs/remotes/origin/TD-47-branch-support-for-jenkins-file
Checking out Revision 254283fa3269536868e557c21d9be155a3f22af3 (TD-47-branch-support-for-jenkins-file)
Commit message: "Changing archive stage branch detection"

When its private:

> git.exe fetch -no-tags --progress https://bitbucket.org/interplx/accesslayer.git +refs/heads/TD-47-branch-support-for-jenkinsfile:refs/remotes/origin/TD-47-branch-support-for-jenkins-file
