권한이 거부되었습니다(공개 키, gssapi-keyex, gssapi-with-mic) - Hetzner VPS(macOS)

(macOS) ssh 섹션에 공개 키를 추가하여 Hetzner(ubuntu 20.04)에서 VPS를 설정했습니다 ssh-keygen -t rsa. 그런 다음 연결을 시도 ssh -i ~/.ssh/id_rsa x.x.x.x하지만 권한 거부 오류가 계속 발생합니다 Permission denied (publickey,gssapi-keyex,gssapi-with-mic). 동일한 방식으로 Oracle 클라우드 인스턴스에 연결하는 데 문제가 없습니다.

방화벽을 비활성화하고 키에 대한 파일 권한을 변경하는 등 온라인에서 찾을 수 있는 거의 모든 것을 시도했습니다.

프로젝트에 액세스할 수 있는 친구도 Putty를 사용하여 연결하고 있으며 문제 없이 연결할 수 있습니다.
