위와 같이 에러가 발생해 있다

구글링을 해보니 ssl 관련 보안강화로 인해 접속이 안되는 증상이 발생한단다 ssl 관련 셋팅은... 복잡하니 그냥 예전 방식으로 셋팅을 하자

Admin Console > Server > Server Settings > Security Settings > Client Connection Security

항목에 

Custom:

Old SSL method: Available

TLS method: Not Available

수정하고 save setting 하고 클라이언트 접속 시도 하면 정상적으로 접속이 된다.
