[LetsEncrypt] SERVFAIL looking up CAA for domain

iVPS 영은파더♥ 2019.04.12 17:47

Let's Encrypt 로 무료 인증서를 발급 받을려고 했더니 "DNS problem: SERVFAIL looking up CAA for ..." 에러 메시지가 뜨면서 더 이상 진행이 안되네요~

직접 네임서버 운영으로 해결했습니다.

# certbot certonly --standalone --agree-tos -m email@address -d www.example.kr
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator standalone, Installer None
Starting new HTTPS connection (1): acme-v02.api.letsencrypt.org
Obtaining a new certificate
Performing the following challenges:
http-01 challenge for www.example.kr
Waiting for verification...
Cleaning up challenges
Failed authorization procedure. www.example.kr (http-01): urn:ietf:params:acme:error:dns :: DNS problem: SERVFAIL looking up CAA for www.ivps.kr

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: www.example.kr
   Type:   None
   Detail: DNS problem: SERVFAIL looking up CAA for www.example.kr

CAA 레코드를 지정하고 난 뒤에 인증서 발급이 되네요~

 

www.example.kr.        CAA 0   issue   "letsencrypt.org"

/var/named/example.kr.zone 파일에 위의 필드를 추가하고 named 재시작 하고 인증서 발급해보세요~
