You can use the wildcards `\*.quay.io` and `*.openshiftapps.com` instead of `cdn0[1-3].quay.io` and `rhcos-redirector.apps.art.xq1c.p1.openshiftapps.com` in your allowlist.
When you add a site, such as `quay.io`, to your allowlist, do not add a wildcard entry, such as `*.quay.io`, to your denylist.
