Support for a canonical name?

I’m trying to get this set up on my company’s GitLab server, and I’m having an issue getting the certificate to generate. I get the following error:

   Type:   unauthorized
   Detail: Error parsing key authorization file: Invalid key
   authorization: 145 parts

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A record(s) for that domain
   contain(s) the right IP address.

I believe this is because the domain name points to, rather than our IP address. Is there a way to get this working without actually using the IP address?

You could set it as an A record, rather than a cname

Alternatively you could verify via DNS

so CNAMEs are forbidden?

why that?
CNAMEing is very helpful.

Validation process works great here with CNAMEs using webroot

I figured out the issue; it was something stupid on my part. I wasn’t mapping the webroot correctly.
