How to resolve below issue. whenever i call web service , iam getting below error every time. if i try this url in the browser , i can able to retrive the services. i am attachement the screen shot as well. i tried to given username and password but even not working. i am getting same error.
Hmm, with the current information it is hard to give an advice. The URL format should work.
You could try to dig into the web response by using Fiddler - Free Web Debugging Proxy - Telerik
If you don't want to do that on your own I suggest you open a ticket at Nintex Support.
