Prova questo script che verifica la tua connessione e segnala l'errore MySQL effettivo. Potrebbe essere utile determinare se le credenziali che ti sono state fornite funzioneranno o quale parte del processo non riesce. Dato che lo stai utilizzando su un host web remoto, ti consiglio di codificare il nome utente e la password del database per evitare di passarli in chiaro su Internet aperto.
