"The host appears to be running but port "-1" does not respond. " error when testing connection to Rule Execution Server from Decision Center

Troubleshooting


Problem

In the Decision Center Configure tab, under Manage Servers, when I test the connection to the server instance of the Rule Execution Server, I see the error: Test failed for server foo. The host appears to be running but port "-1" does not respond.

Diagnosing The Problem


Resolving The Problem

  • Make sure that the server connection details are correctly specified ( hostname, portnumber, username/password) in the Decision Center Configure tab, under Manage Servers.
  • Ensure that you set the URL of the Rule Execution Server to be http://<host>:<port>/res, not http://<host>:<port>/testing
  • Check that the port is not being used by another process. If it is, stop the other process.
  • Make sure that the user belongs to a Decision Center group that has privileges to access a RES server
  • Make sure that the SSP application (jrules-ssp-<appserver>.ear) has been installed correctly on the application server, and has been started.
  • Test the availability of Decision Validation Services by typing the URL in your browser: http://<host>:<port>/testing
  • Make sure there is no firewall blocking the HTTP/HTTPS connection from Decision Center to Rule Execution Server
