백업에서 복구 후 SSO 세션 타임아웃 발생

지원
1

새로운 머신으로 Discourse를 이전하는 중입니다. 백업으로 Discourse를 재구성하면 정상적으로 작동하지만, 로그인(관리자든 일반 사용자든)을 시도할 때마다 세션 타임아웃(Session Timeout) 메시지가 표시되어 로그인이 되지 않습니다. 어떤 로그나 설정을 확인해야 할지 모르겠으니, 문제 해결을 위해 도움을 주실 수 있으신가요?

지금까지 브라우저 캐시와 쿠키를 삭제하고, 호스트, Docker 컨테이너, SSO 제공자의 시간대를 동일한 시간대로 재설정했으며, rails 콘솔을 통해 DiscourseConnect를 비활성화한 뒤 로컬 로그인으로 시도해 보았습니다.

감사합니다!

여전히 이 문제로 막혀 있습니다. SSO에서 항상 “Nonce has expired”(Nonce 만료) 메시지가 뜨는데, 어떻게 디버깅해야 할지 모르겠습니다. SSO 제공자로 Nextcloud 인스턴스를 사용 중이며, 이 앱을 사용하고 있습니다. 이전까지는 항상 정상적으로 작동했습니다.

production.log의 예시를 하나 여기에 올립니다:

SSO 프로세스 시작/Nonce 생성부터 sso 매개변수 제공까지의 시간 차이는 단 24초뿐입니다. 어디서 에러/문제를 찾거나 더 나은 디버그 정보를 얻을 수 있는지 아이디어가 있으신 분 계신가요?
