A failed cPanel or WHM login is nearly always one of five things: the wrong address, the wrong password, your IP blocked after too many attempts, a two-factor problem, or a suspended account. Check them in this order and you'll usually be back in within minutes.
Before you start
- Your MdmHost client login, so you can use the dashboard's one-click access.
- The cPanel username from your welcome email (it is not your email address).
Use one-click login from the dashboard
The fastest route skips passwords entirely: sign in to the MdmHost dashboard, open Services, choose the hosting or reseller service and click Login to cPanel or Login to WHM. See Log in to cPanel from the MdmHost dashboard. If that works, the problem was the URL or password.
Check the login address and port
| Panel | Address |
|---|---|
| cPanel | https://yourdomain.com:2083 or https://yourdomain.com/cpanel |
| WHM (resellers) | https://yourdomain.com:2087 or https://yourdomain.com/whm |
| Webmail | https://yourdomain.com:2096 |
If your domain doesn't resolve yet (new domain or recent nameserver change), use the server hostname from your welcome email instead. Office and public Wi-Fi networks often block ports 2083/2087; the /cpanel and /whm addresses use the normal HTTPS port instead.
Reset the password
- In the dashboard, open Services → your service and use the password change option, or click Reset Password on the cPanel login page if it's enabled.
- Use a new, strong password and save it in a password manager.
- Resellers can reset a customer's cPanel password in WHM → Account Functions → Password Modification.
Check whether your IP is blocked
After several failed logins, cPHulk or the server firewall blocks your IP. Symptoms: the page times out or says brute force protection, while the site still works from mobile data.
- Find your public IP with the IP checker.
- Stop trying for 15–30 minutes; many blocks expire on their own.
- If it continues, open a ticket with your IP so support can unblock and whitelist it.
Tip: Saved, outdated passwords in an email app or FTP client keep failing in the background and re-trigger the block. Update them after a password change.
Two-factor authentication problems
- Codes are time-based: make sure your phone's clock is set automatically.
- Lost the phone? Support can remove 2FA from the account after verifying you own it. Resellers can do this for customers in WHM.
Account suspended
If the page says the account is suspended, check for an unpaid invoice in the dashboard or a suspension notice by email. Paying the invoice unsuspends the service automatically.
Troubleshooting
- "The login is invalid": wrong username or password. The username is the cPanel username, not your domain or email.
- Login page loops back: clear cookies for the domain or try a private window.
- SSL warning on port 2083: use the server hostname, which has a valid certificate.
- Webmail only: see Fix webmail login problems. Resellers: WHM reseller login guide.
