I am getting the error when configuring a Call Web Service task. The credentials that I am supplying in the configuration of the task have access through the proxy and to the web service. If I paste the URL of the web service into a browser, the call works and I get the expected response, just not from the Call Web Service task.
I tried using the Web Request Task as well and I get the same result.
Is there somewhere I need to set up separate credentials that the Call Web Service task will use for proxy access?
