Frequently Asked Questions

How do I test my Nginx configuration before reloading?

Run `sudo nginx -t` in your terminal. If the syntax is valid, safely apply changes using `sudo systemctl reload nginx`.

What headers are required for WebSocket proxying in Nginx?

You must include `proxy_set_header Upgrade $http_upgrade;` and `proxy_set_header Connection 'upgrade';`.
