Hi all. I have spent almost a full day in the docs & trying things, and I can’t seem to figure out what might be happening here.

None of the CNAME records from my DNS zones are propagating. Every other kind of record—A, TXT, SPF, and MX work just fine and fully propagate.

This issue applies equally to all domains.

I am using the Linode one click installer to install CyberPanel, and after trying everything else I spun up a new Linode and the same issues occurred with CNAMEs on a fresh install.

Any advice on where to look would be greatly appreciated, thanks in advance!
