@fefrei님의 오프라인 페이지 추가 조언을 따랐는데, 이는 완벽하게 작동했습니다. 하지만 이것이 이 문제와 관련이 있는지 확실하지 않습니다.

이 오류를 수정하기 위해 시도해 볼 수 있는 방법에 대한 추천이 있다면 감사하겠습니다. 예를 들어, 이것이 SSL 인증서 관련 오류인지 확인할 수 있는 방법이 있을까요? 포럼의 나머지 부분은 정상적으로 작동하는 것 같습니다.

이것은 이름이 존재하지 않음을 의미하며, 즉 지정하신 버킷이 존재하지 않는다는 뜻입니다. 아마도 올바른 버킷 이름이 설정되어 있지 않은 것 같습니다.

3

도와주셔서 감사합니다만, 그게 원인인 것 같지는 않습니다. S3의 이름은 다음과 같습니다:

image
image904×242 10.2 KB

Discourse의 이름은 다음과 같습니다:

image
image930×110 10.1 KB

실제 오류 메시지는 다음과 같습니다:
image

4

아, 서버의 관점에서는 해당 이름이 존재하지 않는 것입니다.

서버의 DNS를 수정하여 이름을 해석할 수 있도록 해야 합니다.

5

감사합니다. 확인해 볼 만한 명백한 위치나 명령어가 있을까요?

예를 들어, 이 테스트를 명령줄에서 어떻게 재현할 수 있나요?
서버에서 이 명령을 실행하면 403 오류가 발생합니다:

wget lacomunidad-nachotime2.s3.amazonaws.com
6

이 작업을 앱 컨테이너 내부에서 수행해야 합니다:

$ host lacomunidad-nachotime2.s3.amazonaws.com
lacomunidad-nachotime2.s3.amazonaws.com is an alias for s3-1-w.amazonaws.com.
s3-1-w.amazonaws.com has address 52.217.37.148
7

사실 이미 작동하니까 다른 문제일 거예요 :thinking:

$ /var/discourse/launcher enter app
host lacomunidad-nachotime2.s3.amazonaws.com
lacomunidad-nachotime2.s3.amazonaws.com is an alias for s3-1-w.amazonaws.com.
s3-1-w.amazonaws.com has address 52.216.176.51

수정: 아까 Discourse에서 S3를 다시 활성화해 봤더니 에러가 사라진 것 같아요. AWS 쪽에 문제가 있었던 건가요? :person_shrugging:t2:‍:male_sign: 어쨌든 도움 주셔서 감사합니다. host 명령어를 알게 되었어요 :blush:
