Getting a 401 Unauthorized after upgrading to Web API 2.0 and Microsoft.Net.Http 2.2.15

Hi all,

I'm suddenly getting 401 Unauthorized errors after having upgraded to Web API 2.0.

I have made no other changes except upgrading to Web API 2.0 on the server and Nuget package "Microsoft HTTP Client Libraries" version 2.2.15 on the client (Silverlight).

The 401 errors appears to happen randomly, which makes it really hard to debug.

Anyone else having issues with this upgrade?

-Thanks!

Edit : I get an 401.2 Unaouthorized: Logon failed due to server configuration.
