How To Fix cPanel Error “IP Address Has Changed”

If you found this post helpful, kindly share it and show your support :)

The most probable reasons of this error message “IP address has change” from cPanel are as follows.

  • Your Internet Service Provider (ISP) may has a short DHCP lease time which causing your IP address to be renewed/released and reassigned while you are logged into cPanel.
  • You are attempting to login into cPanel using the same account from two different server concurrently.

To resolve this error, you can try to relogin into cPanel. This usually works. If it is not working, you will need to configure cookie IP validation settings from WHM.

Note :- It is applicable for accounts with WHM/cPanel version 11.28 and above and you will have a Cloud Hosting Reseller Account or higher.

To do the same, you can follow below steps.

  • Login to WHM
  • Click on Tweak Settings under Server Configuration
  • Click on “Security” tab
  • Change “Cookie IP Validation” value from strict to loose and frequency of re-authentication will be lowered.
  • Click on Save Button

Note :- This will validate the IP addresses used in all cookie based logins to limit the ability of attackers who capture cPanel session cookies to use them in an exploit of the cPanel or WebHost Manager interfaces. For this setting to have maximum effectiveness, service subdomains (formerly known as proxy domains) should also be disabled. If you skip this, you will have to utilize a proxy server with a static IP address to establish and maintain your connection.

To disable service subdomains,

  • Go to “Domains” tab under Tweak Settings
  • Change the value from “On” to “Off”.
  • Click on Save button

That’s it.

On my website, you can find solutions for different Web-hosting-related problems. Sometimes, I spent hours searching/googling to find a solution. This inspired me to start a website that gives solutions to different Webhosting problems. This website includes basic Linux and windows commands, and different control panels like cPanel, Plesk, DirectAdmin, Webmin & so on. You can find solutions and or suggestions for different Web-hosting related problems from here. Hence I would like to say Errorlogz is your server protector.  I will be glad if Logdetect can help any one of the Server admins to find a solution to his problem.
