Can't connect to Dynamics 365 using Microsoft.Xrm.Tooling

Can somebody (hopefully from Europe region, so crm4.dynamics.com) confirm if it is possible to connect to online organizations using CrmService client? The following code simply stopped working today:

var service = new CrmServiceClient("Url=contoso.crm4.dynamics.com; Username=someone@contoso.onmicrosoft.com; Password=password; authtype=Office365");
Console.WriteLine(service.IsReady);


IsReady is false and service is not authenticated (there is an error of null reference exception when trying to perform any action using this service). I checked multiple online instances (all in crm4 region) and all of them work (or in this case - don't work) the same. Just looking for some confirmation if this is a common problem before I raise a ticket for Microsoft.

    Tested it, and had to add https:// to the url make it work on an EMEA-instance. Got a nullreference to the organization name otherwise. This is on a v9.0 with SDK v 8.2.

    {"Organization cannot be null or empty.\r\nParameter name: Organization Name"}
