Discourse 로그인 시 소켓 작업에서 "알 수 없는 오류" 발생

제품 지원 자체 호스팅

로그인 시 "unknown error"라는 오류 메시지가 발생합니다. 로그 파일을 확인해 보면 세션을 열 때某种 CSRF 문제인 것 같습니다 (POST 요청이 403 응답을 유발함) 하지만 실제 근본 원인은 이해하지 못하겠습니다.

운영 환경 구성:

  • SSL 종단을 위해 haproxy 로드 밸런서가 사용됨
  • 로컬 Docker 호스트에서 Apache가 리버스 프록시로 사용되며, 로컬 WebSocket(web.socketed.template.yml)으로 트래픽을 전달함
  • 데이터와 web_only를 위한 별도 컨테이너를 가진 현재 Discourse 환경
  • haproxy에서 Apache로, 그리고 Apache에서 web_only 컨테이너 내부의 nginx로 RemoteIPHeader X-Forwarded-For를 통해 원래 IP 주소가 전달됨 (forwardfor)

이 설정을 추가로 디버깅하는 방법에 대한 아이디어가 필요합니다. web_only 컨테이너 설정:
