Apache2 config to Nginx config? - apache

Question

I have 2 ports running on my server right now.
that is the main application port 5455
socket port 8433
we are migrating this apache setup to Nginx.
In Apache, we had 2 conf files 1 for the application server and 1 for the socket
I have been able to move the application server correctly but not able to make the socket work
<VirtualHost _default_:8443>
ServerAdmin admin#abc.tech

</VirtualHost>
My current Nginx file is as below
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;
}
}
so when the application hits the below route
https://api.abc.tech:8443/socket.io/?EIO=3&transport=polling&t=MvOh2
it is returning below error
