systemd를 통해 Fedora 34에서 openvpn 클라이언트를 시작하는 방법은 무엇입니까?

그래서 Fedora 34에서 openvpn 클라이언트를 시작하는 데 문제가 있습니다.

터미널에서 이런게 나오네요

[root@mybox ~]# systemctl start openvpn-client@default

[root@mybox ~]#

내 구성 파일은 다음 위치에 있습니다.

root@mybox client]# ls -al
total 12
drwxr-x---. 1 root openvpn   60 Aug  9 03:47 .
drwxr-xr-x. 1 root root      60 Aug  9 03:47 ..

[root@mybox client]# pwd
/etc/openvpn/client

default.conf의 내용은 다음과 같습니다.

[root@mybox client]# cat default.conf

시스템화된 서비스입니다.

로그에서 뭔가를 얻을 수 있기를 바라며 "--verbose 9 --log /var/log/openvpn.log"를 추가했습니다. 그러나 "systemctl start"를 실행한 후에도 /var/log/openvpn.log가 존재하지 않습니다. 또한 서비스 파일을 편집한 후 "systemctl daemon-reload"를 실행하고 있습니다.

"ExecStart"의 값을 사용하여 openvpn을 수동으로 시작하면 오류가 발생하지 않습니다.

어떤 아이디어가 잘못될 수 있나요? 감사해요!

업데이트 1:

1. 테스트로 Fedora 구성(인증서 + .conf + 자격 증명) 파일을 Manjaro 라이브 USB에 복사했습니다. pacman을 통해 openvpn을 설치하고 아무 문제 없이 systemd를 통해 OpenVPN을 시작했습니다.
2. 또 다른 테스트로 Manjaro 라이브 USB의 .service 파일을 Fedora 설정으로 복사하고 Fedora를 교체했습니다.[이메일 보호됨]그리고 여전히 systemd를 통해 OpenVPN을 시작할 수 없습니다.
