Thanks for the solution in the second post livewire, I was having the exact same problem, just had to use mysql.x10hosting.com as the database host. (+ rep for that)
Database server hostnam: mysql.x10hosting.com
Port: leave blank
Database name: your account name_DB name (for me (diesel_xxxx)
Database username: your account name_Database username what is given to it (for me its diesel_xxxxx)
Database password: usernames password
Prefix......:leave it like it is
