Hello @Prathibha.Mariyappa,

Is the client per chance behind a firewall?

That would be the most common reason, why the connection is refused.

If that is the case, try our Java example that includes proxy handling (DSS2TokenProxy, DSS2TokenPorxyAuth, depending if the proxy requires a proxy username and password spec) , it shows how to specify the proxy to interact with DSS from behind the firewall.
