Hello community,

After the latest update of cPanel to version 66.0.10, I am experiencing an issue with the cPanel cache. Problem is the following:

When, I access the WHM and click on any menu, I am being logged out and see the "401 Authorization" cPanel page. After entering the root password, I am logged into the WHM again. On second click on the menu, I wanted initially to visit I am being logged out on the default WHM login page. After third authentication, I am able to access the menu.

I have already contacted the cPanel support team and they provided the following temporary fix:

mv /var/cpanel/caches/ /var/cpanel/caches_old && service cpanel restart

This indeed fix the issue, however in 24 hours, I have to perform this several times and it is quite annoying.

Does anybody encounter the same problem? Do we have other fix, which will last for more time, until the next cPanel version is out and fix this problem?

Any thoughts are well appreciated, thank you in advance!

Hello @KrasniyRus,

Internal case CPANEL-14475 will address an issue where accessing the links on the left navigation menu within WHM can result in the "HTTP error 401 Security Token" error message when the security token changes. A resolution is expected before cPanel 66 reaches the "Release" build tier. You can monitor the cPanel 66 change log to see when the resolution is published:

66 Change Log - Change Logs - cPanel Documentation

In the meantime, the workaround command you referenced will need to be ran each time you encounter the issue.

Thank you.
