wcf hosting in godaddy server

Question

i have one doubt..after i hosted wcf service in godaddy server,i tested it using wcf testclient i get all functions properly but when i invoke it i get an error "Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.".......can anyone please help me to solve this?
