unblock withn flush-hosts

To unblock a host using the "flush-hosts" command, you need to have administrative access to the MySQL server. Please follow these steps:

1. Connect to the MySQL server using the command-line client or suitable MySQL client application.
2. Log in as an administrator with appropriate privileges.
3. Execute the following command to view the blocked hosts:

   SHOW VARIABLES LIKE 'blocked_host';

This will display a list of blocked hosts.

4. Identify the host you want to unblock from the list.

5. Flush the blocked host using the following command:

   FLUSH HOSTS;

This will remove all blocked hosts from the list.

Please note that you should exercise caution when unblocking hosts, as it can potentially expose your MySQL server to security risks.
