Add Web Reference from remote web service – Error "Failed to add a Web Reference."

Hi Daniel,

I can confirm that firewall rules are set up OK. As I can hit the site and call the web service and receive a response via a c# application that the remote company sent me. I also can add internal web services successfully. The two blogs you sent me did not assist. I’m wondering if VS.Net needs other ports opened apart from HTTP.

Below is the web service I’m trying to hit. I’ve replaced host, company names with x’s It looks good to me so I don’t understand why it want add.

POST /global/data/xxxx_integration.asmx HTTP/1.1
Host: xxxxxxx.xxxxx.net
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://www.xxxxxxxxx.com/webservices/xxxxx_Integration"
