我的服务器上现在有2个端口正在运行。

1. 这是主应用程序端口5455
2. 套接字端口8433

我们正在将该Apache设置迁移到Nginx。 在Apache中，我们有2个conf文件1个用于应用程序服务器，1个用于套接字

我已经能够正确移动应用程序服务器，但是无法使套接字正常工作

我当前的Nginx文件如下

server {
    listen 8443;
    server_name _;

    location / {
        proxy_pass http://localhost:8443;
    }
}

server {
    listen 80 default_server;

    server_name _;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl default_server;

    ssl_certificate /etc/letsencrypt/live/api.abc.tech/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/api.abc.tech/privkey.pem;

    root /var/www/html;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name api.abc.tech;

    location / {

     proxy_set_header   X-Forwarded-For $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header   Host $http_host;
         proxy_set_header X-NginX-Proxy true;
     proxy_pass         http://localhost:5455;

        if ($request_method = 'OPTIONS') {
                add_header 'access-control-allow-origin' '*';
                add_header 'access-Control-Allow-Methods' 'GET,POST,OPTIONS';
                add_header 'access-Control-Allow-Headers' '*';
                add_header 'access-Control-Max-Age' 1728000;
                add_header 'Content-Type' 'text/plain; charset=utf-8';
                add_header 'Content-Length' 0;
                return 200;
            }
    }

    location ^~ /.well-known/acme-challenge/ {
            allow all;
        }
}

因此当应用程序到达以下路线时

https://api.abc.tech:8443/socket.io/?EIO=3&transport=polling&t=MvOh2

它返回错误以下
