패널을 설치해서 사용중이었습니다. 도메인을 3개 세팅해서 사용했는데요 패널이 아이피로 접속이 되는데 서브도메인으로 연결하였습니다.
패널이 그 기능이 있습니다.
그런데 이렇게 하면 DB메뉴를 클릭하면 접속이 되지 않더라고요. 클플의 Proxy를 켜고 사용한것이 잘못된것인가 싶었습니다. 8443 포트로 접속합니다.
패널 설정에서 ssl을 사용함으로 설정했는데 문제가 발생했습니다.
그래서 패널을 제어할때 안되는 경우 ssh로 접속해서 메뉴에 접근할 수 있습니다. 그래서 ssl사용안함을 선택했는데 그때 부부터
Web server is down Error code 521
이 발생합니다. 아이피를 변경해봐도 마찬가지입니다.
에러로그입니다.

해결할 방법이 있을까요? 포멧하고 다시 패널을 설치중이긴 한데 클플에서 변경된 아이피를 적용해도 마찬가지네요
어쩔 수 없이 Proxy끄고 다시 세팅해볼려고 합니다.
최악은 dnszi를 이용해야 할거 같습니다.
클플 Proxy를 통해서 8443 포트로 접속할 경우 SSL 사용이 강제됩니다.
따라서 서버에서 SSL을 사용하지 않는다면 에러가 납니다.
패널에서 SSL을 사용함으로 설정했을 때 에러가 난다면 그 에러를 잡는 것이 우선이겠지요.
문제의 원인이 분명히 있는데 그걸 해결하려고 하지 않고 다른 꼼수(클플 Proxy)로 우회하려고 하니까
우회책에서도 마찬가지로 문제가 발생하는 겁니다. 눈에 보이는 증상만 달라질 뿐...
네임서버를 바꾼다고 해결될 가능성은 정확히 0.000%입니다.
