인프런 커뮤니티 질문&답변

test.py 작성 시 AuraDB에 접속이 안 되서 막혀 있습니다.

이전에도 질문해 주신 분이 계셨던 것 같은데요.

.env 파일에 URI, USERNAME, PASSWORD 정확히 썼고요
(browser.neo4j.io 접속해서 위 정보 복사해서 붙이니 잘 되는 것 확인했습니다.)

분명 제 PC 문제일 것 같은데, 유사 해결사례가 있으시면 조언부탁드립니다. 수업을 시작할 수가 없네요. ㅠㅠ

(방화벽 off 시도, PC 재부팅 시도 )

    password=os.getenv("NEO4J_PASSWORD"),
