NodeJS + Plesk + nginx + HTTPS (wss://)

Connecting to a WebSocket server via WebSocket Secure connection (wss://) on a Plesk based host.

Create a subfolder or subdomain

As I'm going to have only one NodeJS, I prefer a subdomain: sockets.example.com If you will have several NodeJS Apps you may want something like example.com/socket1, example.com/socket2, ...

Optional: disable PHP

As I will only use NodeJS on that subdomain, and I will redirect all traffic to NodeJS, it is safe to disable PHP

Apache & nginx Settings

Disable Proxy mode

Turn that option off to stop using Apache

Add additional nginx directives

location / {
	proxy_pass http://127.0.0.1:3000;
	proxy_http_version 1.1;
	proxy_set_header Upgrade $http_upgrade;
	proxy_set_header Connection "upgrade";
}

Profit

Now you can run your NodeJS (on port 3000 for the above example)

You can also use Plesk's Node.js extension

• link 2

This way you do not have to add additional nginx directives but you still have to disable proxy mode.
