내가 무엇을 하든 tryhackme 서버에 SSH로 접속할 수 없습니다. [닫기]

내 Linux 컴퓨터(Linux Mint 21.1 Cinnamon)에서 tryhackme의 SSH 서버에 연결하는 데 문제가 있습니다. 터미널에 포트 22 연결 시간 초과 오류가 표시됩니다.

터미널 출력은 다음과 같습니다.

제한된 기술로 이 문제를 어떻게 해결할 수 있습니까?

• OopenVPN을 올바르게 구성하고 .ovpn사이트에서 파일을 올바르게 가져왔으며 사이트 액세스 페이지에 연결된 것으로 표시되었습니다.
• SSH를 허용 ufw하고 입력 및 출력 체인을 허용했습니다. SSH 구성 파일을 망쳤습니다( 로 ForwardX11설정 됨 yes, ForwardX11Trusted로 설정 됨 no).

파일을 로드할 때의 출력은 다음과 같습니다 .ovpn.
