Nignx 反向代理，POST 請(qǐng)求返回 403 錯(cuò)誤

使用 Nginx 反向代理 Pinterest 這個(gè)網(wǎng)站，網(wǎng)站可以正常打開，但是POST請(qǐng)求出錯(cuò)。

查詢了很多資料，仍然沒有找到出錯(cuò)的原因在哪里，請(qǐng)大神幫我看看，Nginx 配置文件內(nèi)容如下:

server {
    listen 80;
    listen 443;
    listen [::]:80;
    listen [::]:443;

        sub_filter_once off;
    }
}
