How To Fix “IP Address Has Changed!” Error in cPanel

  WHM

Introduction

The “IP Address Has Changed!” error in cPanel occurs when your session IP changes during login. This can interrupt access to both cPanel and WHM.

Prerequisites

  • Access to cPanel and WHM
  • Valid login credentials

Implementation

There are two possibilities why you would receive the error message “IP address has changed” from cPanel.

  1. Your Internet Service Provider (ISP) has a short DHCP lease time, causing your IP address to be renewed/released and reassigned while you are logged into cPanel.
  2. You are attempting to log in to cPanel with the same account on two different devices simultaneously.

There are two ways to resolve the error message.

Method 1:
Log in to cPanel again, which usually resolves the issue.

Method 2: Configure Cookie IP Validation Settings

  1. Log in to cPanel and WHM.
  2. Go to → Server Configuration → Tweak Settings → Security Tab

3. Look for Cookie IP Validation

  • Click the “?” icon for details
  • This setting validates IP addresses used in cookie-based logins

4. Change the setting to loose.

  • This reduces the frequency of re-authentication
  • You can also disable it completely if required

5. Disable proxy domains

  • Otherwise, you must use a proxy server with a static IP

6. Clear your browser cache and log in again

Conclusion

By adjusting cookie IP validation settings in WHM and re-logging into cPanel, you can resolve the “IP Address Has Changed!” error and maintain a stable session.
