    Description

      After update Zabbix Proxy from 4.0.6 to 4.2.0 active checks of net.dns crash Zabbix agent.

      Zabbix Agent service is not starting, until net.dns check will be disabled.

      Local checks via cmd  (zabbix_agentd.exe -t net.dns[10.1.124.4,domain.local,A]) is OK, agent successfully returns data.

      zabbix_get from Zabbix Proxy (zabbix_get -s server3.domain.local -k net.dns[10.1.124.4,domain.local,A]) also crashes Zabbix Agent, after execution zabbix_get prints following error:
      zabbix_get [18854]: Get value error: ZBX_TCP_READ() failed: [104] Connection reset by peer
      zabbix_get [18854]: Check access restrictions in Zabbix agent configuration
       
      Downgrading of Zabbix Agent not solving problem.
