i tried multiple times the Task:
Install Packages Using a Jenkins Job
Each Time i got Issues with adding the App-Servers to Jenkins, this Time at least stapp03 worked and finished the build but the other 2 doesnt work, i tried FQDN and IP but failed all time:
I did all the Steps i got from the Review (failed first time) and it worked on one Node only
Frustrated about this task and leave it as failed now but would be happy when this could be looked after or others may had the same Issues.
