curl可以工作，但是nginx反向代理不起作用

Question

到代理服务器的卷发有效，但是当我尝试通过nginx反向代理使其工作时，甚至没有请求到达另一台服务器。

这是我的卷发，

Below is my nginx.conf

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log debug;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       9001 default_server;
        listen       [::]:9001 default_server;
        server_name  _;
    ssl on;
    ssl_certificate /etc/nginx/ssl/ca.crt;
    ssl_certificate_key /etc/nginx/ssl/ca.key;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

#   root /;

    location / {

        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header Host example-proxy.yola.com;
        proxy_pass https://example-proxy.yola.com:443;
        include /etc/nginx/role-token;
    }
    }

    server {
    listen 9002 default_server;
    server_name _;
    location / {

    root /;
    }
    }
}

在尝试

时

curl -d@test.xml -k https://localhost:9001/bio/V2/moderate?appId=ronga -vvv

它抛出以下错误

我尝试在proxy_pass的末尾添加斜杠，还尝试将完整的url路径添加到proxy_pass，但没有一个起作用。另外，我还没有在Nginx错误或访问日志上看到任何内容。我真的很感谢有人可以提出建议。
