WCF client error

Question

I'm having trouble to consume my WCF service that is hosted on an web IIS (IIS 8.0). I can access the .svc page and add reference to the service on my WPF application, but when I call/invoke some of the wcf service methods, i got an exception:

There was no endpoint listening at mywebsite.com.br/blusync/BluService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.System.Net.WebException: The remote server returned an error: (404) Not Found.\r\n at System.Net.HttpWebRequest.GetResponse()\r\n at System.ServiceModel.Channels.HttpChannelFactory`1.HttpRequestChannel.HttpChannel‌​Request.WaitForReply(TimeSpan timeout)

Since the address is correct, I assume the error is being caused by some security/authentication issue.

Here is an example of how i'm using the method:

MyServiceClient client = new ServiceClient();
client.Open();
client.GetDate();
client.Close();

Here`s my app.config on the client app:

    <?xml version="1.0" encoding="utf-8" ?><configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IBluService" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://www.mywebsite.com.br/blusync/BluService.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IBluService"
                contract="BluService.IBluService" name="BasicHttpBinding_IBluService" />
        </client>
    </system.serviceModel>
</configuration>

My WCF is hosted on an web host with IIS 8.0 and I set the framework to 4.0, and i'm publishing the project through ftp.

I tried a lot of different bindings, but I'm a newbie in this technology.. Please, help me guys, i'm stuck in here!
