asp.net mvc - Inner exception Fault Exception: Authentication Failure

Question

An unsecured or incorrectly secured fault was received from the other party. See the inner Fault Exception for the fault code and detail.

I am integrating crm to my web application. I can login through browser with my credentials, but i am getting error while I am connecting through MVC web application.

Here is my code:

IOrganizationService organizationService;
ClientCredentials authenticationCredentials = new ClientCredentials();
authenticationCredentials.UserName.UserName = "*****@*****.onmicrosoft.com";
authenticationCredentials.UserName.Password = "*******";
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
Uri organizationuri = new Uri("https://*******.api.crm4.dynamics.com/XRMServices/2011/Organization.svc");
OrganizationServiceProxy serviceProxy = new OrganizationServiceProxy(organizationuri, null, authenticationCredentials, null);

organizationService = (IOrganizationService)serviceProxy;
if(organizationService!=null)
{
    Guid userid = ((WhoAmIResponse)organizationService.Execute(new WhoAmIRequest())).UserId; //  I am getting the error in this line.
    if(userid!=Guid.Empty)
    {
        Console.WriteLine("Connection established successfully");
        return organizationService;
    }
    else
    {
        Console.WriteLine("Failed to establish");
    }
}

return organizationService;

I have checked the time zone. Both are same and I am using trial version of crm.
