If you have accidentally failed to log into cPanel a few times, the server may block your IP address. These blocks are put in place to protect the server (and your website) in case of malicious attacks. If you haven’t failed too many login attempts, but still see an IP address block, it may have been caused by a mail client or an FTP program attempting to connect with the incorrect credentials.
If your IP address is blocked, you will see the following error when you try to log in to your hosting:
Your connection to this server has been blocked.
IP blocks can be caused by failed login attempts or port scanning.
Most blocks are temporary, but can be permanent for repeated attempts.
Please contact firstname.lastname@example.org for further information.
Your blocked IP address is [your IP)
This server's hostname is [your hosting server]
If you see this error message, do as it says and contact email@example.com with as much information as you can provide — such as your domain name, username, IP address, etc. — and we will help you regain access to your account.
