I’m looking into paying for a domain, so that an auto-renew of the https cert can happen through the DNS challenge. In my current setup, I’m just using a dyndns through No-IP, but that means I’m forced to verify through the port and not through DNS. After a quick search, I’m interested in signing up for a domain through Google Domains.
However, I don’t see Google Domains listed in the list of providers that a DNS challenge can be done on:
Can anyone confirm that a domain from Google Domains would work with automatic https on Caddy? Specifically when the cert is auto-renewed with Let’sEncrypt? If it would not work, does anyone have an alternate suggestion on where I could purchase a domain name for a similar price?
The registrar your domain is registered with is not relevant for the purposes of the ACME DNS challenge. For instance, inaptbox.com (my blog) is registered with Namecheap, but its DNS is serviced by DigitalOcean. In my case, I’d verify my domain with the DigitalOcean provider, not Namecheap.
What you need to do is use one of the supported DNS providers. I personally have used the DNS from Linode, DigitalOcean, Namecheap and Cloudflare, but your mileage may vary. Ultimately, the choice is up to you.
