SAP-XI-Webservice scenario

Hi,

I have following scenario: SAP triggers a proxy to XI which calls a webservice. Right now proxy from SAP reaches XI, however i get following error when trying to consume the web service on third party server : com.sap.aii.af.ra.ms.api.DeliveryException: Connection closed by remote host.

This is a secure webservice for which we have done neccessary configuration on XI side. Not sure if this error is because of something missing in the configuration or something else.

The target url in SOAP adapter which points to the wsdl is viewable in browser.

Please advise.

Thanks

Anand
