I'm pretty sure about my CDN provider supports WebSocket forwarding, all of my other functions worked except General Settings.

@PitaJ

Here is the full image of my error.

My network structure is: CDN (using HTTPS but HTTP to origin) =====> Nginx Proxy =====> NodeBB

do you guys have discord or telegram group?

It's hard to communicate through a forum.

@PitaJ

NodeBB: 1.14.2
Nodejs: 12.18.3
Database: Mongodb 4.2.8
Nginx config:

server {
    listen 80;

    server_name forum.ackystack.com;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://10.0.0.71:4567;
        proxy_redirect off;

        # Socket.IO Support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

Errors in the browser console:

WebSocket connection to 'wss://forum.ackystack.com/socket.io/?EIO=3&transport=websocket' failed: Error during WebSocket handshake: Unexpected response code: 502

currently using Nginx as a proxy server, and also tried others.

please help find out what's wrong, I've been worked on this thing 5 hours.
