[htcmarket]

Hi,
I have some problem when I try connect to remote DB from server:
Error!: SQLSTATE[HY000] [1042] Can't get hostname for your address

I am use PDO connection(php)
In local virtual server - I success connected, but in production - no!
Can some one help me, please

Fix the connecting machine's reverse DNS , make sure you have RDNS added and resolving to the right IP.
You should also issue a FLUSH HOSTS statement on the MySQL server.
