You are not using SFTP (but FTP or FTPS)
You are not using port 1022
You are using the wrong username or password
You have used the wrong username and password too many times.
After 10 failed login attempts, you will be blocked for 10 minutes. If you fail 30 times during 1 hour, you will be blocked for an hour. Keep in mind that many clients can try to sign in multiple times using different settings on it's own, so 3-4 wrong connection attempts can in some cases be enough to get blocked.
To overcome this problem, set a new SFTP password in the control panel and make sure all your settings are correct (SFTP, port 1022 and the correct hostname, username and password!)
