build를 했는데 publicIPs에 8080 포트를 주소에 입력하면 "연결을 거부했습니다." 라는 문구가 뜹니다.8080 포트가 쓰이지 않는 거 같아 cat nohup.out을 입력해보면

org.postgresql.util.PSQLException: FATAL: password authentication failed for user "jjeong"
        at org.postgresql.core.v3.ConnectionFactoryImpl.doAuthentication(ConnectionFactoryImpl.java:693) ~[postgresql-42.6.0.jar!/:42.6.0]

#datasource
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/membercertification

url, username, password가 다 들어맞는 것도 확인했습니다. build.gradle

어디가 문제인지 모르겠습니다 ㅠㅠ
