Unable to load URL

Hello Everybody

I am getting 'Unable to load URL'  when I paste WSDL url into Web Service Query and press 'Import' button

Following are steps I followed

1. Created a Webi report from Bex query

2. Published a Web service URL

3. Opened a blank Xcelsius Dashboard, and data manager window from Connections and pasted WSDL URL and clicked 'Import'

then I am getting an error as >> Unable to load URL

http://xxxx:8080/dswsbobje/qaawsservices/biws?WSDL=1&cuid=AcA6UcrYvnlBpw5haeXuDLI

I also tested the above url in web browser and its returning proper xml

any help would be greatly appreciated. I am supposed to show some changes in dashboard by today evening

Thanks

Sandeep
