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
Thats what i did as well, multiple times and i was able to login via ssh from jenkins to all app servers but when i add it in Jenkins UI i get failures. I skipped this one now as frustrating experience and hope to get a new Task soon
