El servidor ByetHost pasa valores html "Comprobando su navegador" con JSON String
Al intentar analizar la cadena json en Android, se pasan los valores HTML. Antes de un día, todo funcionaba bien, y de repente mi aplicación comenzó a fallar al tratar de recuperar una base de datos con la ayuda de archivos php.
Cuando lo comprobé noté que los valores html ... ver logcat

Esto está sucediendo en todas las páginas que he alojado en byethost server, mientras que las páginas que están alojadas en otro servidor funcionan bien y bien. Intenté mover uno de mis archivos a otro servidor y en eso está devolviendo la cadena json adecuada.
Además, cuando verifico la url en el navegador, devuelve la cadena json adecuada sin ninguna excepción o error con byethost ... pero en Android da valores html ...
Aquí está mi clase de función JSON
