Issue/Introduction

When attempting to install or start an AS400 Agent, the Agent fails with the following:

20200218/181122.957 - U02000012 Connection to Server '1.2.3.4():2217' denied.
20200218/181122.957 -           3447 - A remote host did not respond within the timeout period. >Socket.cpp#net::Socket::connect(const InetAddress &) const:29<
20200218/181122.957 - U02000010 Connection to Server '1.2.3.4:2217' terminated.
20200218/181123.987 - U02000072 Connection to system 'AUTOMIC' initiated.

Cause

The Agent and Automation Engine are unable to connect to each other

Environment

Release : 12.3

Component : Automation Engine

Resolution

Please make sure ports are open on both sides and the Agent can communicate. This is easily tested by attempting a telnet from the Agent to the Automation Engine

Additionally, make sure the ports referenced (in the above 2217) are the active CP ports for your Automation Engine.
