Commented Issue: Getting Error while trying to configuere the site URL: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. [19265]

I'm using a SharePoint List Destination in SQL Server Integration Services. When I try to configure the site URL, via the advanced editor, I get the message see below.
I can access the Sharepoint via Browser or with the HTTP Connection Manager for HTTP Connections without any problems. Visual Studio is running as an Administrator. All Our Servers are running with NTLM authentification, i don'T know why the package is trying to establish a 'Negotiate' Connection. I'm looked in to the server with my AD-Account.

Any Ideas so solve this Issue?

The authentication header received from the server was 'NTLM'. ---> System.Net.WebException: The remote server returned an error: (401) Unauthorized.

I am getting this error even when we start building the data flow. Any solutions found?
