Hello,
is there any specific reason why zabbix item with key "net.tcp.port[1.2.3.4,9443]" is always returning "0" even if port is open and I can telnet to it without trouble with command "telnet 1.2.3.4 9443".
When I try to monitor other service running on port 443 it works without problems, but monitoring of port 9443 always return 0 no matter if port is open or not.
