Listen for http and https on same port and serve same content to both

Question

I have a situation where I need to listen for http and https on same port(8099) and serve the same content to both http and https requests. My config file for https is given below. I have tried adding listen 8099; to the server block but thats not helping.

worker_processes  auto;

events {
    worker_connections  4096;
}


http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    proxy_connect_timeout 3200s;
    proxy_read_timeout 3000s;
    #gzip  on;

    server    {
       
    listen               8099 ssl http2;
    ssl                  on;
    ssl_certificate      C:/cert/letsencrypt.crt; 
    ssl_certificate_key  C:/cert/letsencrypt-decrypted.key; 
    #ssl_protocols TLSv1.2;
    ssl_buffer_size 4k;   
    ssl_session_tickets off;    
    ssl_session_cache shared:SSL:5m;
    ssl_session_timeout 60m;    

    access_log off;

        location / {
            try_files $uri $uri/ /index.html;
                  }
                  
        location /ort/{
        
            proxy_pass http://localhost:8042;
            proxy_set_header Authorization "Basic YWxuYXNnjiiBhY3M6YWxuYXNhcnBhY3M1Nzc=";
            proxy_set_header HOST $Host:8099/ort/;
            proxy_set_header X-Real-IP $remote_addr;

            rewrite /ort(.*) $1 break;
                           }              
       
    }}
