If it has changed suddenly without you doing anything, has your supplier setup a hardware firewall, or done something else with the firewall?
Another thought, in cpanel (for the site that is hosting the database) under mysql (bottom of page), is the IP address of the connecting site shown under "Allowed Host"?
If not you will need to add it, could also be that the connecting sites IP address has changed you'll need to check.
Hope you get it sorted.
