我正在 Raspberry Pi 4 上運行 Ubuntu 20.04 LEMP 伺服器。
2023/05/29 11:51:40 [emerg] 3356#3356: cannot load certificate "/etc/letsencrypt/live/postfixadmin.mysite.com/fullchain.pem": BIO_new_file() failed (SSL: error:0200100D:system library:fopen:Permission denied:fopen('/etc/letsencrypt/live/postfixadmin.mysite.com/fullchain.pem','r') error:2006D002:BIO routines:BIO_new_file:system lib)
我假設這意味著 Nginx 無法存取我的憑證。然而，我的網站postfixadmin.mysite.com仍然運作良好。此錯誤到底表示什麼？
