ssh to demo01.typo3server.ch does not work

I added a manual job to the to the pipeline called Get dump for Content Master.

When i run the job it fails with the following message:

ssh: connect to host demo01.typo3server.ch port 22: Address not available

see this job for details

When i run the commands locally it works, so i assume it's an issue in the runner/docker container not being allowed to connect or maybe i configured the job wrong.

services/demo.typo3.org/site#60

So my question is, how to get this job to do what it is supposed to: Dump the DB and fileadmin so it can be used later for local development.

Thank you!
