Problema conexión base de datos remota

[vanepd]

Hola

Tengo una base de datos en un servidor "icdsoft", ya habilitada para acceso remoto.

Por otra parte intento conectarme a esa base de datos desde otro servidor "aruba", mediante phpbb de un mkportal con los datos de acceso remoto que me proporciona el servidor en el cual se encuentra la base de datos.

Sin embargo tras un largo rato de página en blanco cargando, me sale:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

El código mediante el cual conecto es:
