Jenkins start but doesn´t seem to execute anything?

I have a RuntimeEngine (node-locked) licence, and with that I set up a Jenkins Pipeline with a buildstep to execute my existing TestSuiteCollection (with 1 testcase, which should break after 40 sec). The reality looks more like this:

And this goes on for half an hour, until the job finally dies without executing anything (I also cannot cancel it, I don´t understand why)).

Can anyone tell me what happens here? Why does the testcase doesn´t execute via Jenkins?

Thanks a lot, can´t figure it out for almost 5 hrs now…

Do the account linked to the -apiKey= command-line argument is correctly set on TestOps ?
