Environment

Release : 9.3.x, 9.4.x

Component : CA Automic Applications Manager (AM)

Cause

While there are different "connection" errors, a "connection timed out" generally means that the connection is not reaching the apache webserver host or the Applications Manager master's host.

Resolution

The issue is likely a network issue such as a firewall issue.

One test is to ping the master or apache server host/IP address to make sure a connection can be made. 

The IP/Host value can be found in the connections.properties file and taking a look at the IP/Host entry for the Applications Manager instance you are trying to connect to.

Below is an example of the ping command failing with also a timed out error. If the below error is seen, please refer to the network admin as the issue is likely network or firewall related.
