WHM/cPanel Shows "Cannot Read License File"

If WHM and cPanel suddenly stop loading and show an error like this, your hosting is not gone and your account has not been suspended:

Cannot Read License File

To access the interface, you must install the license and ensure
that the license is active. The cPanel license server said that a
license could not be issued for your server (66).

This page explains what the message means and how to get it resolved.

What it actually means

cPanel licensing is not a one-time check. Every server re-validates its license with the cPanel license server on a regular schedule. The "Cannot Read License File" error appears when that re-validation does not complete, usually because the connection between your server and the cPanel license server was briefly interrupted. When that happens, the license is temporarily marked inactive and the panel stops loading until it is refreshed.

Three things are worth knowing:

• It is almost never a billing problem on your side. Your hosting subscription and your cPanel license are handled by us, and a paid, active service can still show this error after a momentary connectivity blip.
• It affects everyone at once. Because the license is server-wide, WHM and every cPanel account on that server show the error together. If you are a reseller, expect several clients to report it at the same time. That is normal for this issue and does not mean each account is individually broken.
• It is fixed on the server, not in your account. There is no setting in your cPanel or client area that you can change to clear it.

ℹ

Not a suspension

A suspended account shows a clear "Account Suspended" page, not a license error. "Cannot Read License File" is a licensing/connectivity issue, not an account or payment action.

How to get it resolved

The fastest path is to let us re-validate the license on the server.

1. Open a support ticket and tell us the server or main domain affected.
2. Paste the exact error text you see (including the number in parentheses, such as (66)), which helps us confirm the cause immediately.
3. We re-validate the license on the server and confirm that WHM and all cPanel accounts load again.

This is typically a quick fix once we are on it. You do not need to change DNS, reinstall anything, or touch your account settings.

Reseller tip

If your clients contact you first, you can reassure them that the issue is server-wide and already being handled, then point us at the affected server. There is nothing each client needs to do individually.
