Graphql web socket connection failed over production

I Have tried every possible Nginx config but it's showing connection failed every time.
config file:
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
#try_files $uri $uri/ =404;
proxy_pass http://127.0.0.1:1337;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
}
location /graphql {
proxy_pass https://bakbakgraphql.com/graphql;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
}
Error:

Node Socket Server Errror on nginx server

I have created a socket for my messaging app which is working fine on the local server. Connection and Listeners are working properly.
But When I updated that on the server, Then not able to establish the connection.
I am using pm2 for running ports on nginx server.
This is how my configuration looks like here -
/etc/nginx/sites-available/default
location / {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
location /socket {
proxy_pass http://localhost:3001;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
PS: MY js code seems fine as that is working fine on local server so not adding here. I am assuming it's a problem from here with the configuration

NGINX reverse proxy to node HTTPS

I've got an NGINX server running a reverse-proxy server to a node app.
Now I need to get it working with https but I keep getting 502: Bad Gateway error when trying to access the site at https
server {
listen 80;
server_name MYSERVERDOMAIN;
location / {
proxy_pass http://localhost:3000;

proxy_set_header Connection 'upgrade';

}

Your setting looks correct, so I'm not quite sure about the issue. However, I'm using below setting for my production server with additional config for static assets folder and https auto-forward - which is the ultimate settings you may want for your production servers. Hope that it can help:
server {
listen 80;
server_name example.com;
rewrite ^/(.*) https://example.com/$1 permanent;
}
server {
server_name example.com;
listen 443 ssl default_server;
listen [::]:443 ssl default_server;
ssl_certificate /etc/ssl/certs/www.example.chained.cer;
ssl_certificate_key /etc/ssl/private/www.example.com_ssl_private_key.key;
root /var/www/example/public;
location / {
try_files $uri #proxy;
}
location #proxy {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
