systemd 서비스가 시작되지 않았습니다(권한이 거부됨)

그래서 오늘 저는 ts3 서버를 이전 Windows 상자에서 새로운 centos8 서버로 옮기기로 결정했습니다. 모든 것이 잘 작동하지만 이제 부팅 시 서버가 자동으로 시작될 수 있도록 systemd 서비스 파일을 만들려고 합니다. 서비스 사용자로 시작하려고 하면 모든 것이 잘 실행되지만 루트(systemctl 사용)로 시작할 수는 없습니다. 추가 정보:

"teamspeak" 사용자에게 su를 요청하고 거기에서 startscript를 실행하면 모든 것이 잘 작동합니다. 하지만 시스템이 제대로 작동하지 않는 것 같습니다.

내가 여기서 놓친 아이디어가 있습니까?
