Error in setting resources limits using containerization

I’m trying to set resources limits using containerization. I followed the guidelines provided on this topics
1 – Introduction to Containerization (Website Limits)

But when once I click launch I get the following error
( Operation Failed! Websites matching query does not exist.)
and when I edit and set the required limits I also get the same error.
( Operation Failed! Websites matching query does not exist.)

My question is, what is the cause of this errors and how can I fix it.

containerization doesnt works best all time still you can try and make if work fine. It is limited to CentOS and CentOS is getting end of life soon. Anyways which Centos version are you using here?
Its best to use Cloudlinux for limiting server resources as they have better functions and kernel modifications to handle all these effectively.

Thank you for your comment.
I’m currently using CentOS 7 64bit with CyperPanel

Try with Centos8 or almalinux as Centos7 is too old and many repositories are outdated for centos7 currently

The installation on almalinux 8.5 does not work!
