y ya no trae ningun resultado, alguien sabe como se puede solucionar?

Hola.

El error 500, indica que no existe la URL que estas consultando (en este caso, http://www.servicioscorona.mx/SACCoronaCoatza/JSONDemo/GetClientes).

En este caso, deberas consultar con el proveedor del servicio web, si cambio la URL.

OK Muchas gracias, entonces checare que problema tiene esa url

saludos,
