Removing an IP Address Ban
From WHMCS Documentation
After three consecutive failed administrator login attempts, the system will block the source IP address for the amount of time that you specified in your security settings. This helps to prevent against dictionary password attacks.
Remove the Ban
To resolve this issue, you can wait for the ban to expire at the displayed time on the error message, log in from a different IP address, or follow these instructions to lift the ban immediately:
- Log in to your database administration interface (usually phpMyAdmin via your server control panel).
- Select the WHMCS database in the left-hand menu.
- Browse to the tblbannedips table.
- Locate the row containing your IP address.
- Click the corresponding red "X" icon.
This will remove the ban and you will be able to access your WHMCS installation again.
Whitelisted IPs
If you become banned often, consider adding your connection's IP address to the Whitelisted IPs list in the Security at Configuration () > System Settings > General Settings or, prior to WHMCS 8.0, Setup > General Settings.
