Trigger jenkins button gives Error: jenkins.url: unknown error

[karlitos]

I set up Jenkins and Bitbucket and I am able to trigger the poll manually with curl:

curl -v http://jenkins.url:8080/git/notifyCommit?url=ssh://git@git.url:7999/ian/project.core.git
* Hostname was NOT found in DNS cache
*   Trying 10.201.0.106...
* Connected to jenkins.url (10.201.0.106) port 8080 (#0)

Scheduled polling of ianus.core

The Git-logger shows:

Dez 14, 2015 5:19:35 PM FEIN hudson.plugins.git.GitStatus
Received notification for uri = ssh://git@git.url:7999/ian/project.core.git ; sha1 = null ; branches = []

Triggering the polling of project.core

But in the BitBucket server Gui clicking on the Trigger Jenkins button gives: Error: jenkins.url: unknown error.

I do not know if this is not related to the Issue #105, because I do not have any anonymous access enabled.
