Description 

The package manager is attempting to reach out and get information about updates but is receiving errors from the package mirror servers. This can be due to local issues with the package manager or upstream issues with the mirror servers. You can check any published issues on CloudLinux here:

Cloudlinux statuspage.io

Workaround

You can verify that your package manager is using the most up-to-date information from the mirrors by clearing and updating the cache. Once those are done you can see if a check-update completes successfully:

CL 7 systems:

yum clean all

yum makecache

yum check-update

CL 8 systems:

dnf clean all

dnf makecache

dnf check-update

If this is an upstream issue on the mirror servers, the issue will clear itself up after some time. If the check-update continues to fail, please contact your System Administrator or open a support ticket for a second look.
