Steps to reproduce:

1. Have a check such as net.tcp.service["https","127.0.0.1","15671"]
2. Upgrade Agent2 version from 6.0.42 to 6.0.43

Result:
zabbix_agent2 -t 'net.tcp.service["https","127.0.0.1","15671"]'
net.tcp.service["https","127.0.0.1","15671"]  [s|0]

In the Agent's debug log:

https error: cannot parse the combined url https://[127.0.0.1]: parse "https://[127.0.0.1]": invalid IP-literal

Expected:
When rolling back to 6.0.42:

zabbix_agent2 -t 'net.tcp.service["https","127.0.0.1","15671"]'
net.tcp.service["https","127.0.0.1","15671"]  [s|1]
