If you are using WHM/Cpanel to manage your hosting server then chances are you’ve experienced being lockout by the server already due to Cpanel’s CpHulk brute force protection feature. CpHulk helps deter any attempt to gain access to the server through brute force or password guessing thus if you happen to forget your password and keep logging into the server without success for five consecutive times you will definitely be blocked by the server.
By default, below is CpHulk’s tolerance to failed login attempts:

Even if you’re able to supply the correct login credentials to your server, once you’re blocked from the system, you still wont be able to login to the following services:
- Login to the server through SSH
- Check your email through webmail
- Login to your WHM/Cpanel
What you can do when it happen for you to be able to gain access to the server again are the following:
- Connect to a VPN so you will access the server from an unblocked IP address
- If your Internet service provider is using Dynamic IP assignment then a restart of your modem should get you a new IP address
- Connect to your friend/neighbor’s network — don’t forget to ask permission first.
- Tether your phone
- Contact your server’s technical support to flush your CpHulk’s DB
