Parsing WS-Trust response failed when connecting to SSAS

Question

I am trying to connect to Azure Analysis Services in a small web application. The code that I came up with in Microsoft.AnalysisServices.Tabularis:

Server as_svr = new Server();
String as_conn_str = "Provider=MSOLAP;Data Source=<Server Name>;Integrated Security=SSPI;Persist Security Info=True;";
as_svr.Connect(as_conn_str);

Which uses my Windows Credentials.

Unfortunately I keep getting:

parsing_wstrust_response_failed: Parsing WS-Trust response failed

And more specifically:

    [AdalException: parsing_wstrust_response_failed: Parsing WS-Trust response failed]
   Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext.RunAsyncTask(Task`1 task) +89
   Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext.AcquireToken(String resource, String clientId, UserCredential userCredential) +29

   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +35
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1639

I also tried using:

Server as_svr = new Server();
String as_conn_str = "Provider=MSOLAP;Data Source=<Server Name>;User ID=<UserID>;Password=<Password>;Persist Security Info=True; Impersonation Level=Impersonate;";
as_svr.Connect(as_conn_str);

and it yields the same error. It has to be connected to some security settings, but I do not have any experience in this field.

I would be grateful for any help. Thank you.
