Not able to add HTTPS enabled webservice as Service reference in Visual Studio 2008. Error 403

Question

if in IIS specify "require a clients certificate" while adding a HTTPS enabled WebService as Service reference through Visual Studio 2008, the following exception occured:

There was an error downloading "https://10.95.185.119/service1.asmx". The request failed with HTTP status 403: Forbidden. Metadata contains a reference that cannot be resolved: "https://10.95.185.119/service1.asmx". The HTTP request was forbidden with client authentication scheme 'Anonymous'. The remote server returned an error: (403) Forbidden. If the service is defined in the current solution, try building the solution and adding the service reference again.

In IE i can get WSDL in IE without any problem. If I remove "requirement of the certificate" - all ok!

This problem is repeated when application is running.

help please!

Answer 1

Sounds like you have a proxy between you and the server that requires authentication (windows based I guess). IE will have authenticated in a previous session which is why you're able to see the endpoint.

Visual Studio however, will not have authenticated against this proxy and this is why you're seeing the 403.
