Nginx 如何反代 wss 连接？

我当前的设置时这样的，抄了很多教程，但是不懂原理感觉抄也是白抄，不管用。

server {
        listen 86;
        server_name box.example.com file.example.com files.example.com pan.example.com;
        if ($scheme = http){
                return 301 https://$server_name:88$request_uri;
        }
}

map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;
}

server {
    listen 88 ssl http2;
    server_name box.example.com;
    error_page 497 301 =307 https://$host:$server_port$request_uri;

    ssl_certificate /etc/letsencrypt/live/box.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/box.example.com/privkey.pem;
    ssl_session_timeout 5m;

    ssl_stapling on;

    resolver 8.8.8.8 8.8.4.4 valid=300s;
    resolver_timeout 5s;

    location / {

        proxy_set_header HOST $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "";
        proxy_max_temp_file_size 0;
        proxy_read_timeout 500s;
        proxy_connect_timeout 600;
        proxy_send_timeout 240;
    }

    location /api/command/ {
        proxy_pass http://localhost:8687;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

其实我应该多补充一下：
1 、不是常规端口，是 http 86 ，https 88 。
2 、我用的是 filebrowser ，网页访问各项功能都正常，就是 filebrowser 有个命令行工具可以在网页上使用 shell 命令，这些 shell 命令是通过 websocket 传输的。这个功能无法使用，从浏览器调试看是请求不成功:
```
commands.js:12 WebSocket connection to 'wss://box.hideurl.com:88/api/command/?auth=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.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.gRQ53CHiiESvt7YZN387h5u6pXrvI6jDwoVBTSW_qxg' failed:

3 、我的配置里第一个 location 是 filebrowser 的。第二个 location 是 websocket 的。但是 wss 连接还是不通……
4 、ChatGPT 对此类问题束手无策，会重复无用信息车轱辘话。

### 题外话：
大家可以测试一下问 ChatGPT
```
http://damn.com:86 怎么用 nginx 跳转到 https://damn.com:88
```
ChatGPT 会给你一个错误答案。然后你继续问：
```
你仔细看看你的答案正确吗？
```
ChatGPT 会说：你说的对，我犯了一个错误。正确的配置应该是这样……（把上面错误的代码再发一遍），如果你继续说它的答案不正确，它还会道歉，然后原封不动在给你发一遍刚才的配置……哈哈
