Fresh install at archlinux, postgresql 13.3, timescaledb 2.3.1

I using default templates: Template Module ICMP Ping (Template tooling version used: 0.38),

Template Module Interfaces (Template tooling version used: 0.38)

Steps to reproduce:

1. Add Template Module Interfaces to host (Template Module ICMP Ping will be attached automatically), wait for complete discovery cycle.
2. Simulate "host down" situation (power off host, or add block firewall rule)

Result:
After 3 minutes trigger "Unavailable by ICMP ping" does not work, but trigger "No SNMP data collection" is in effect.

Maybe, zabbix server stops sending icmp requests after the host interface becomes unavailable state.

I checked the same case in version 5.2.6 - no problem
If I use only one template "Template Module ICMP Ping" on host, or host have other interface (agent, for ex) - then there is no problem.
