I am trying to view dashboards created in PPM using mashzone. Version of PPM and Mashzone being used is 9.8 for both. Now - when creating data feed in Mashzone, following error occurs resulting in no data getting loaded and no data source getting created as a result: 

Details of error: 
Unable to load resource "http://<server IP>:<port>/<context>/services/queryApiService?wsdl".

For creating the connection, the values of port and context used were as per the client settings (Server Port and Query Interface respectively). 

Kindly note that the PPM favourites URL that is being intended for use in Mashzone is working when pasted on the browser address bar. 

Request your help and support in resolving this error.
