The Problem: Timeout When Sending Requests

In a typical setup, you have:

A React application running on port 3000

When you try to access your backend from your React app using HTTPS, you may experience timeout errors. This can happen due to the browser's security policies that restrict cross-origin requests, especially when attempting to access specified ports directly.

Example Scenario

You might have executed the following NGINX configuration for your server:

In this scenario, requests sent directly to port 5000 may lead to timeouts, as the browser will not allow it due to CORS (Cross-Origin Resource Sharing) restrictions.

The Solution: Use NGINX Proxy Pass

To fix the timeout issue, you can use NGINX's proxy_pass directive to redirect specific requests from your frontend to the backend seamlessly. Here’s how you can better configure your NGINX setup:

Testing Your Configuration

After updating the configurations, ensure to test your setup:

Restart NGINX: Execute sudo systemctl restart nginx to apply the changes.

Connect to Your App: Try accessing your React app through HTTPS and ensure API requests are functioning without timeout.

Conclusion

Happy coding!
