Ok, I probably found the problem. When I omit disable-host-service-checks dependency, everything works good. I think it’s because the ping4-interconnect dependency fails correctly, but after that disable-host-service-checks dependency check testing host, which is OK and the dependency passes, so notification is sent.

But I’m afraid, I cannot find solution with both dependencies
