Pterodactyl API v1 - Connect to WebSocket

In the config wings (/etc/pterodactyl/config.yml)

change the allowed origins to accept your IP (it will be visible to everyone)

'*' = all (potential security fail)

allowed_origins: [ '*' ]

Restart Wings

sudo systemctl restart wings

On your JavaScript Project

Install dependencies

npm install --save colors node-fetch websocket
