Hello experts,

All configurations are done and i'm able to connect to Service Manager via link. But on logging into SM, getting error in Chat Service Configuration as bellow:

Error calling method: doHttpRequest in class: com/hp/ov/sm/server/utility/HttpClient Exception (java.net.ConnectException: Connection refused: connect)


Checked and verified all Services (Apache, Tomcat, ChatServer, ChatService and SM Services) are running and deployed in same machine.
Able to connect to OpenFire admin console and did specified configurations.
But not able to access the chat service url from Service Manager.

Please help me to get it resolved.
