Zabbix Agent Blocks SSH Remote Access

[eligiable]

I've some remote servers hosted in the cloud and the configuration is:

- the operating system is ubuntu 16.04
- Zabbix agent is 3.4.15 (same as the server)
- Nginx 1.10.3
- PHP 7.0

I have got a total of 8 Servers but 2 of the servers, when I enable Zabbix-agent the ssh remote connection timeout. I've tried to remove templates but the issue remains the same.

The SSH Connection only works (Remote Only) if I disable the Zabbix-agent.

Local Network SSH Connectivity is fine.

If someone has faced a similar problem, please help me to figure out.

Hi!

Did you ever find out what the problem was?

I am unable to connect to my server via SSH as well and the last thing I did on it was configure zabbix-agent, but as I haven't set up a backup access, then for now I can't really be sure about it. Seeing no replies here or any similar thread on the internet, leads me to believe that the problem maybe elsewhere.
