反向代理nginx不加载内容

Question

我正在尝试在 docker 下使用 nginx 设置反向代理，以便能够通过不同的location指令访问“后端”设备（nas 登录页面、路由器登录页面），proxy_pass但我无法弄清楚。我的实际 *.conf（使用特定的 apps.conf）

server {
listen 80;
server_name DDNS_NAME LOCAL_DOCKER_HOST;
location / {
    return 301 https://$host$request_uri;
}
server {
    listen 443 ssl;
    access_log /var/log/nginx/access_log.txt;
    error_log /var/log/nginx/error_log.txt;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_prefer_server_ciphers on;
    ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS +RC4 RC4";
    server_name DDNS_NAME LOCAL_DOCKER_HOST;
    ssl_certificate xxx;
    ssl_certificate_key xxx;
    location / {
        proxy_pass http://LOCAL_DOCKER_HOST:9000/; #portainer
    }
    location /NAS {
        proxy_pass http://NAS_LOCAL; #nas webUI
        proxy_set_header HOST $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

工作location /效率达到了 95%，因为它实际上加载了 Portainer 接口，但是我无法在其中建立控制台连接，似乎 Portainer 在连接到容器的控制台时使用了不同的端口/套接字/其他东西...无论如何，没有它我也可以生存。

该死的是location /NAS...这是一个curl -L DDNS_NAME/NAS -vvvv

它从正确的设备获得答案（因此初始代理有效），因为它被重定向到，*/r51201,/desktop,/login.html但浏览器（或 curl -L）尝试从加载资源DDNS_NAME/r51201,/desktop,/login.html，当然我得到了 404。我为此奋斗了数周，尝试了无限多种 proxy_set_header 组合，但也许我找不到正确的组合。

当然，我调整了输出以隐藏个人信息，我想联系多个人location，但所有人都这样做，所以我只报告了一个
