Having difficulties to connect the OSSEC server with OSSEC agent using private instance in ubuntu 18.04

Question

I have installed the OSSEC server in a public instance and the OSSEC agent in a private instance on AWS in the same VPC. I have successfully installed the OSSEC server and agent, but can't connect the server with the agent. I was referring below link for setup: https://techviewleo.com/install-and-configure-ossec-hids-agent-on-ubuntu/

As @wowbagger mentioned, checking connectivity is a good idea. You probably have to configure your Security Group on AWS to allow connections (inbounds) in your Manager using TCP/UDP protocol and port 1514 (if you didn't change it).
