스프링 메일 전송 오류 해결이 안됩니다...ㅠ

Question

안녕하세요! 스프링부트 3.2.5로 이메일전송 기능을 구현하다가 오류가 해결이 안돼서 질문 올립니다ㅠ 다른 사람들의 컴퓨터에서는 잘 작동이 되는데 (동일한 코드와 메일) 저의 컴퓨터에서만 오류가 발생하네요ㅠㅠ 우선 오류코드는 이렇게 되어있습니다. window11pro를 사용중이고 gmail, 587포트이며 다른 컴터에서는 이메일이 잘 작동되는 것을 확인했습니다ㅠ 포트를 465로 변경을 해서 해봤는데도 동일한 오류가 발생했고, 네트워크도 다른 네트워크를 사용해봤고, 보안프로그램 끄고, 방화벽 설정도 잘 돌아갈 수 있도록 풀어두었는데 동일한 오류가 발생하고 있습니다ㅠ 혹시 저가 어떤 것을 건드려야 해결이 될까요? 윈도우 재설치도 해봤습니다ㅠㅠorg.springframework.mail.MailSendException: Mail server connection failed.
