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: Logs for the probe: ts=2024-04-15T08:35:16.794418Z caller=main.go:190 module=tcp_connect target=:8471 level=info msg="Beginning probe" probe=tcp timeout_seconds=1.5 ts=2024-04-15T08:35:16.794418Z caller=tcp.go:40 module=tcp_connect target=:8471 level=info msg="Resolving target address" target=e ip_protocol=ip6 ts=2024-04-15T08:35:16.794418Z caller=tcp.go:40 module=tcp_connect target=:8471 level=info msg="Resolved target address" target=******** ip=******** ts=2024-04-15T08:35:16.794418Z caller=tcp.go:112 module=tcp_connect target=:8471 level=info msg="Dialing TCP without TLS" ts=2024-04-15T08:35:16.794418Z caller=handler.go:119 module=tcp_connect target=:8471 level=info msg="Successfully dialed" ts=2024-04-15T08:35:16.794418Z caller=main.go:190 module=tcp_connect target=********:8471 level=info msg="Probe succeeded" duration_seconds=0
