HTTP 오류 : HTTP 오류 502 : 프록시 오류 (연결이 거부 됨)

Question

로컬로 devserver를 실행하는 동안 계속해서 Google 애플리케이션 엔진에서 프록시 오류 502 (연결 거부)가 발생합니다. 프록시는 localserver에 전달되지만 여전히 연결을 거부합니다. 나는 MS 윈도우에서 똑같은 오류가 발생했다

, 그래서 우분투로 전환하지만 여전히 나는이 무엇입니까 : 여기

내가 얻고 것입니다. 그리고 Google 앱 엔진 SDK를 1.8.2로 업데이트 한 후에이 오류가 발생하는 경우 이전 버전이 정상적으로 작동합니다.

어째서 이런 일이 일어 났을까요?

미리 감사드립니다.

Answer 1

글쎄, 나는 프록시를 사용하고 있었고 GAE/Python Snippet은 서버를 실행하기 전에 업데이트를 확인하고 프록시를 사용하여 업데이트 서버를 찾을 수 없었습니다. 그게 왜 내가 그 오류를 얻었는지. 프록시없이 네트워크를 사용하기 시작했고 정상적으로 작동하기 시작했습니다. :).
