ssl 인증서 오류인듯 함

DNS상에 실제 등록된 서버와 인증서간의 서버 도메인은 일치하나 주소가 달라서 생기는 문제로 추정

시도

DNS 서버를 타야하는 상황에서 미리 DNS 서버에 해당 도메인이 바라볼 리소스 수정
이후 해당 인스턴스 내에서 docker-compose 이미지 실행전 인증서 받는 과정 진행 (스크립트 실행)
그리고 docker-compose 실행 후 확인 >> 실패

hosts 파일확인
기존에 local 환경에서 테스트하기 위해 domain을 localhost로 등록해두었음
/etc/hosts, c:\Windows\System32\drivers\etc\hosts에서 해당 domain 제거

domain 접근 가능 및 https, ssl 적용 완료!

항상 windows와 wsl내의 hosts파일 모두를 같이 수정할 것
