Issue/Introduction
Attempting to start an agent from the AWI Administration -> Agent & Groups section results in a popup stuck on “Starting agent…” for quite a while until an Error popup comes up showing:
Connection to Service Manager ({smgr IP}:{port}) failed: ‘java.util.concurrent.ExecutionException: java.io.IOException: java.net.ConnectException: Connection timed out: connection’.
Looking at the service manager log confirms that CAPKI is available by finding the line:
U00022071 CAPKI Library available.
Running the ucybsmcl command from the linux server where the agent is located shows the list correctly:
./ucybsmcl -c GET_PROCESS_LIST -h {smgr IP}:{port} -n AUTOMIC
Running the same from the windows server where the AE is installed shows an error:
*ERROR 2* Pipe returned error
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
When running a telnet command: telnet {smgr IP} {port} from the linux agent server is able to connect
Running a telnet command from the windows server to the linux agent server on the service manager port returned something like:
Connecting To {servicemanager IP}...Could not open connection to the host, on port {port}: Connect failed
Environment
Components involved:
AWI -> Administration -> Agents & Groups
Service Manager
Version:
21.0
Cause
A firewall is blocking the IP and port between the AutomationEngine server and the agent server
Resolution
Contact the networking and firewall team to see what needs to be done to allow bi-directional communication between the Automation Engine server and the service manager server on the service manager port
