I have node.js app which is served by NGINX. I can’t connect socket.io. I got 404 for POST request for establising socket connection.
It’s working locally, so it must be an NGINX problem.
# HTTP - redirect all requests to HTTPS:
server {
listen 80;
listen [::]:80;
return 301 https://$host$request_uri;
}
# HTTPS - proxy requests on to local Node.js app:
server {
listen 443 ssl http2;
server_name example.com;
ssl on;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_set_header X-Forwarded-Proto https;
proxy_pass http://127.0.0.1:8080;
proxy_ssl_session_reuse off;
proxy_set_header Host $http_host;
proxy_cache_bypass $http_upgrade;
proxy_redirect off;
}
}
Thanks for any help.

Let’s run a test, replace your
location / {}
block with this one:It’s a bit more detailed, but it’ll definitely tell us whether or not the issue is with NGINX or the app. If the above doesn’t work, there’s an issue somewhere in the app. If it does work, then we shouldn’t need to do anything else :-).
I would, however, recommend replacing:
with:
It too is a little more detailed, but worth making the change to ensure specifics are added.
Once you’re done making changes, restart NGINX and test the connection.
Try adding the Connection and Upgrade headers as described in the NGINX docs:
along with the following inside the
http {}
block and outsideserver {}
(you can just add it at the top of your virtual host config above theserver {
line):Make sure to restart nginx so that the changes take effect. Does that help?
@kamaln7 I try to add the first block and it seem’s nothing changed, but can you please be more specific with the second one.
@jtittle I replace config with the following and again nothing changes.
Thanks guys for taking the time.
@jtittle Thank you for taking the time.
Yes, my app is listening on that port.
It look’s like the output is blank in error log nothing is reffering to socket connection.
Here is the client request response. https://snag.gy/GUM2s5.jpg
@MakiJS
Is your socket.io application listening on
127.0.0.1
and port8080
? If so, please run:and post the output to a code block as you did with your server block. If it’s not, you’ll need to make sure the application is listening on that IP and port, otherwise it won’t work.
