SSL certificate issuance fails after DNS update: HTTP-01 NXDOMAIN and CLI 449

Hello Vercel team,

Our project bfgc-yaar-community uses www.community.bfgc.kr as a 308 redirect to community.bfgc.kr. Vercel reports that certificate issuance failed because the HTTP-01 challenge encountered NXDOMAIN for www.community.bfgc.kr.

The external DNS now has a CNAME for www.community.bfgc.kr pointing to b6a7e0143b043add.vercel-dns-017.com, and Google Public DNS previously returned the CNAME and Vercel IP addresses. The domain has been added to the project, but browsers have shown a certificate name mismatch.

Retrying vercel certs issue www.community.bfgc.kr --scope chon1029s-projects initially returned the ACME NXDOMAIN error; subsequent attempts returned HTTP 449 / Response Error. The meaning of 449 is not clear from the CLI output.

Could a Vercel engineer please check the current domain validation and certificate issuance status, explain the 449 response, and advise or help reissue a valid certificate? Thank you.
