WCF问题，客户端无法调用服务器端！！！！

在本地调用没问题，但到服务器上就报错“无法处理消息。这很可能是因为操作“http://tempuri.org/IServiceOutPats/GetOutPats”不正确，或因为消息包含无效或过期的安全上下文令牌，或因为绑定之间出现不匹配。如果由于未处于活动状态导致服务中止了该通道，则安全上下文令牌无效。若要防止服务永久中止闲置会话，请增加服务终结点绑定上的接收超时。”

求大神指导 
客户端代码：

 <system.serviceModel>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true"/>

    <bindings>

      <wsHttpBinding>

        <binding name="WSHttpBinding_IServiceOutPats">

          <security mode="None"></security>

        </binding>

      

      </wsHttpBinding>

    </bindings>

    <client>

      <endpoint address="http://160.100.1.246:81/HCSWebService/GetPatInfo/ServiceOutPats.svc"

        binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IServiceOutPats"

        contract="sa.IServiceOutPats" name="WSHttpBinding_IServiceOutPats">

        <identity>

          <servicePrincipalName value="160.100.1.246" />
