Custom domain with subdomain with Vercel

1

Hi,

I’m trying to get my custom domain api.boilerplate.live to work with Render. Unfortunately I am getting a “Certificate Error”.

  • I’m using boilerplate.live with Vercel and api.boilerplate.live with Render.
  • Domain is hosted with Namecheap
  • I’ve set up a CNAME record in Vercel’s dashboard pointing to boilerplate-api.onrender.com

Any thoughts on what I could be doing wrong?

Thanks!

Hi Amos,

Thanks for reaching out.

It appears the boilerplate.live domain has a CAA records limiting certificate issuance to Let’s Encrypt:

$ dig boilerplate.live CAA +short
0 issue "letsencrypt.org"

You’ll need to also add permission for DigiCert as covered in the Custom Domain documentation.

Hope that helps

Alan
