WordPress站点uploads目录图片404无法访问，求排查建议

已完成的排查步骤 #

文件权限与归属验证 #

-rw-r--r-- 1 www-data www-data 394446 Dec 25 09:10 pony.jpg
文件路径：
/srv/rufus/david_public_html/wp-content/uploads/2022/12/pony.jpg

Nginx配置确认 #

站点核心location规则如下：

location / {
   try_files $uri $uri/ /index.php?$args;
}

访问目标图片时的Nginx错误日志：

"GET /wp-content/uploads/2022/12/pony.jpg HTTP/2.0" 404 548 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36" "-"

当前疑问与尝试 #

我怀疑是Nginx的try_files指令导致问题，但uploads目录外的图片能正常加载。比如我曾修改规则为：

try_files $uri $uri/ /wp-content/uploads/$uri /index.php?$args;

期望依次尝试请求URI、带尾斜杠的URI、uploads目录下的对应文件，最后转向index.php，但问题依旧。

奇怪的是主题目录下的图片可正常访问，例如：

-rw-r--r-- 1 www-data www-data 103639 Dec 24 23:06 david_public_html/wp-content/themes/twentytwentytwo/assets/images/flight-path-on-transparent-d.png

可以通过对应链接正常打开，说明问题仅出在uploads目录。

完整访问日志片段：
