A brute force attack is detected when someone repeatedly attempts (and fails) to log into a service on a server. The login page can block the connecting IP for 15 minutes and stop users from logging in for 5 minutes. It is possible to be blocked for up to 30 minutes, depending on the type of attack.
The only solution is to wait for that time to expire and then retry your login. If your login does not work after waiting 30 minutes, please contact Smart Host. so we can investigate the issue.
