I have a Zabbix server running 6.4.12 and an agent running the same version.
Within the same server local ranges (10.250) all of my agents connect without an issue. However, then I expanded to ranges outside of that lab (10.173) and had the firewall team open up 10050 between them.
I am able to telnet from either side back and forth to 10050 so the port is open as requested.
However, when I check the logs on the agent when it's unable to connect I get this message:
I have been back and forth with firewall and they say everything is open, it's being rejected by the 10.250 address which is the server.
Any help would be appreciated as this is driving me crazy.
UPDATE:
Using Debug I got this, does not help me to fix it but more information possibly:
