Hello All,
I run a Zabbix server within one of my local to me LANs and I run my 3CX server in the cloud. I was hoping to gain more insight into my 3CX server by connecting it up to my Zabbix server. Unfortunately I can't get the 3CX zabbix-agent to successfully connect. After adding the host in the Zabbix web GUI the availability indicator turns red with the following error message: "Get value from agent failed: cannot connect to [[199.195.252.150]:10050]: [4] Interrupted system call".
I have a feeling there is something on the 3CX system (iptables?) that's blocking me. I was hoping someone here has solved the problem I am up against before and can give me some tips as I have been working on it on and off for days.
NOTE: IPs have been slightly obfuscated
Zabbix Server
Firewall: Behind pfsense firewall. Port 10051 has been opened for the 3CX servers external IP
UFW: Port 10051 from the WAN IP of my 3CX server has been opened.
Local IP: 11.0.105.1
WAN IP: 73.154.152.100
Server Web UI Host Config:
- Hostname: acsv (same as hostname on 3CX server)
- Groups: Linux Servers
- Interfaces: 199.195.252.150 IP 10050
- Template: Linux by Zabbix agent
- Encryption: None (I plan on using PSK once I can get the connection to initiate)
- Enabled: Checked
Output of sudo ufw status numbered: attached

zabbix-agent Config:

- ServerActive=73.154.152.100

Output of sudo iptables -L -n: attached
Other points to note:
- The Zabbix server has no other hosts reporting issues. I have one other cloud VM hosted on the same platform (BuyVM) and it's not reporting errors.
- tried installing the zabbix-agent from the built in 3CX customized source list AND through a direct .deb package. (installed fine but no change in connection) (tried this as one of last steps)
+ package URL: https://repo.zabbix.com/zabbix/5.0/...x-release/zabbix-release_5.0-1+buster_all.deb
- I usually use UFW instead of iptables since it's easier for me to understand. Could this be causing conflicts?
