FastCGI 在 stderr 中发送：“主脚本未知”，同时从上游读取响应头

需要帮助在新服务器上找到问题。我正在使用 nginx php-fpm 和 varnish 运行 magento 网站。网站一片空白，只有“文件未找到”的文本。

我在 nginx 日志中收到错误

2022/12/17 12:06:25 [error] 166796#166796: *4 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 127.0.0.1, server: sample.com, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/php-fpm/sample.com.sock:", host: "sample.com"

在访问日志中：

[17/Dec/2022:12:31:14 +0100] "GET / HTTP/2.0" 404 36 "-" "Mozilla/5.0

这是站点 nginx conf 文件：
