I'm trying to use socket.io with my nginx reverse proxy server, but it seems not working..
Chrome showing this wonderful waterfall:

and server's response is always like this:
96:0{"sid":"UU9d1DfZL5RD29kAAACq","upgrades":["websocket"],"pingInterval":25000,"pingTimeout":5000}2:40
nginx.conf:

}
}
socket.io server:
const io = require("socket.io")(1027);
io.on("connection", (socket) => {
console.log('connected');
});
front-end javascript:
let socket = io("https://socket.my.domain");
socket.on("connect", () => {
console.log(socket.id);
});
Server keep logging the message 'connected', but client doesn't log the message.
What's wrong with my code?

I am facing an issue with the WebSocket protocol. I am using Django channels/daphne. Everything is working normally on the development local server. I think the issue is with NGINX settings. The error code is 1006
Here is the reverse proxy that I am using:
location ~* \.(js|css|jpg|png|jpeg|html)$

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;

}
Error:
I have configured nginx for ssl-client-authentication. It is working fine for GET and POST (with out payload). But when we use POST with body, client is not passing the certificate.
Either nginx is not asking for the cert
Or the client(javascript) itself is ignoring the cert i'm not sure

I would like to use NGiNX to proxy pass the following:
https://something.com/node.js/foo/bar/baz
into this:
https://something.com:3000/foo/bar/baz
I have successfully done it with the following NGiNX config:
location ~ /node.js/(.*) {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-NginX-Proxy true;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "";
add_header Cache-Control "public";
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_http_version 1.1;
proxy_pass http://127.0.0.1:3000/$1$is_args$args;
}
location / {
try_files $uri /index.php$is_args$args;
}
The problem is the following: when I instantiate socket.io with the default path, it serves socket.io.js here:
https://something.com/node.js/socket.io/socket.io.js
So far so good, but then this javascript tells the client to make requests here, which fail for obvious reasons:
https://something.com/socket.io/...
So then I try to instantiate socket.io with the path option like so:
io.listen(server, { path: '/node.js/socket.io'} );
But the problem is that now the socket.io.js file is hosted here:
https://something.com/node.js/node.js/socket.io/socket.io.js
Is there a way to tell socket.io.js where to host the file socket.io.js but still use the given path?
What is the normal solution to this proxy_pass stuff with socket.io??
Well different ways to solve your issue but I would use below one
location ~ /node.js/(.*) {
rewrite "^/node.js/node.js/(.*)$" /node.js/$1 last;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-NginX-Proxy true;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "";
add_header Cache-Control "public";
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_http_version 1.1;
proxy_pass http://127.0.0.1:3000/$1$is_args$args;
}
location / {
try_files $uri /index.php$is_args$args;
}
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_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;
}
}
server {
listen 443 ssl;
server_name MYSERVERDOMAIN;

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_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;
proxy_cache_bypass $http_upgrade;
}
