mongodb 셋팅 오류

오류 때문에 귀찮게 해드려 죄송합니다..
비밀번호 문제인가 해서 제일 간단한 1234로 변경하고 아이디는 'kim968'로 변경하고 진행했습니다..
'mongodb+srv://kim968:1234@cluster0.gjme16c.mongodb.net/?retryWrites=true&w=majority'

디비 비밀번호를 잘못 입력 했을 경우 서버 접속은 잘 됩니다
'mongodb+srv://kim968:12342@cluster0.gjme16c.mongodb.net/?retryWrites=true&w=majority'

비밀번호를 제대로 입력했을 경우 서버연결이 안 됩니다.. ㅠㅠ
