Laravel Websockets - 无法完成 TLS 握手：无法设置私钥文件

如何解决Laravel Websockets - 无法完成 TLS 握手：无法设置私钥文件

我正在尝试使用 WSS 访问。在 .env 文件中设置证书和私钥文件路径。但低于错误

UnexpectedValueException {#1506
  #message: "Unable to complete TLS handshake: Unable to set private key file `/var/www/html/storage/ssl/private.key'"
  #code: 0
  #file: "./vendor/react/socket/src/StreamEncryption.PHP"

}

我们已经添加了具有正确权限的私钥路径，但是当 Web 套接字客户端尝试连接到 Web 套接字服务器时它仍然显示这一点。
