CRM 2011 Online via an ASP.net application does not work, same code via Console Application Works -> "Authentication Failure"-error - asp.net

Question

I'm trying to connect to a CRM 2011 Online environment. I'm able to connect via a "Console Application", but when I'm trying to connect via an "ASP.net"-application with the same code, it doesn't work, it gives me the "Authentication Failure"-error ({"An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail."}).
Is there something special we need to do to make it work on an "ASP.net" environment. I tested out several solutions I found on the internet, but all gives me the same error.
A "code"-snippet of my simplified code:
private static ClientCredentials GetDeviceCredentials()
{
return Microsoft.Crm.Services.Utility.DeviceIdManager.LoadOrRegisterDevice();
}
protected void Button1_Click(object sender, EventArgs e)
{
//Authenticate using credentials of the logged in user;
string UserName = "*****"; //your Windows Live ID
string Password = "*****"; // your password
ClientCredentials Credentials = new ClientCredentials();
Credentials.UserName.UserName = UserName;
Credentials.UserName.Password = Password;
Credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
//This URL needs to be updated to match the servername and Organization for the environment.
Uri OrganizationUri = new Uri("https://*****.crm4.dynamics.com/XRMServices/2011/Organization.svc"); //this URL could copy from Setting --> Developer Source
Uri HomeRealmUri = null;
//OrganizationServiceProxy serviceProxy;
using (OrganizationServiceProxy serviceProxy = new OrganizationServiceProxy(OrganizationUri, HomeRealmUri, Credentials, GetDeviceCredentials()))
{
IOrganizationService service = (IOrganizationService)serviceProxy;
OrganizationServiceContext orgContext = new OrganizationServiceContext(service);
var theAccounts = orgContext.CreateQuery<Account>().Take(1).ToList();
Response.Write(theAccounts.First().Name);
}
}
I tried several things, like deleting the content of "LiveDeviceID"-folder an re-running the device registration tool. but is weird that it works in the "console application" but not on my "asp.net"-solution...
PS : I am able to generate the "context"-file via crmsvcutil.exe /url:https://org.crm4.dynamics.com/XRMServices/2011/Organization.svc /o:crm.cs /u:username /p:password /di:deviceUserName /dp:devicPWD

Is there any particular reason you have
Credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
You shouldn't need that line for windows live authentication.
Even with that the code seems valid so it is something to do with the Device Registration. I suggest rather than just call it directly like you have
using (OrganizationServiceProxy serviceProxy = new OrganizationServiceProxy(OrganizationUri, HomeRealmUri, Credentials, GetDeviceCredentials()))
{
You try something like the following because you only need to register once:
ClientCredentials deviceCredentials;
if ((CRMSettings.Default.DeviceID == String.Empty) || (CRMSettings.Default.DevicePassword == String.Empty))
{
deviceCredentials = Microsoft.Crm.Services.Utility.DeviceIdManager.RegisterDevice();
}
else
{
deviceCredentials = new ClientCredentials();
deviceCredentials.UserName.UserName = CRMSettings.Default.DeviceID;
deviceCredentials.UserName.Password = CRMSettings.Default.DevicePassword;
}
using (OrganizationServiceProxy serviceProxy = new OrganizationServiceProxy(OrganizationUri, HomeRealmUri, Credentials, deviceCredentials))
{
I have had issues in the past where I get an "already registered" response from the RegisterDevice call.
I would also dump out the Device ID and Password so you can see if they are being set.
