What logging output did you get from adding &debug=true to the probe URL?

no change

What did you do that produced an error?

What did you expect to see?

If probe is succeeded, why where are only zeto values being returned?
This behaviour does not emerge vor all probes, but often (ca 20%). The same blackbox_exporter but for linux, which is configure for the same target doent have the same problem.

What did you see instead?

This ist a log from the probe:
