WCFServices

We have a WCF Service which is used by External Clients to call some methods inside it.

Most of time they don't have any issue but sometimes, they are getting below error

There was no endpoint listening at http://abcd.net/xyzAPI/pqrs.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.-inner:The remote server returned an error: (404) Not Found

Client Developed application using C#4.0: Below is client config file.

<system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="Basic" />
               
            </basicHttpBinding>
          
        </bindings>
        <client>
          <endpoint address="http://abcd.net/xyzAPI/pqrs.svc"
                binding="basicHttpBinding" bindingConfiguration="Basic" contract="IntigralServiceClient.IUUCPAPIServer"
                name="Basic" />
          
        </client>
    </system.serviceModel>

Please let me know any changes in configuration file will help me in avoiding the intermidtae 404 error that my client is facing.
