Apache 2.4 SSL 구성 - 서버가 HTTP 400 요청을 거부합니다.

Apache 2.4 구성에 문제가 있습니다. 입장https://subdomain.my-domain.com이 http 400은 항상 반환됩니다.

잘못된 요청 귀하의 브라우저가 이 서버가 이해할 수 없는 요청을 보냈습니다. 원인: SSL 지원 서버 포트로 일반 HTTP를 보내고 있습니다. 대신 이 URL에 액세스하려면 HTTPS 체계를 사용하세요.

내 사이트는 https를 통해 직접 액세스하므로 http에서 https로의 리디렉션이 필요하지 않습니다. 아래는 내 아파치 구성입니다. 인증서의 유효성을 확인하지 않는 것으로 알고 있습니다. 지금은 자체 서명되어 있지만 앞으로는 바뀔 것입니다.
