What I have tried so far:

Verified Server is Running:

The server starts and logs “Server is running on http://localhost:4000” and “database connected”.
Checked for Code Issues:

Ensured there are no syntax errors or unhandled exceptions in my code.
Increased Logging:

Added console logs in the controller to trace request handling.
Firewall and Port Issues:

Allowed Node.js through the Windows firewall.
Opened port 4000 in Windows firewall settings.
Tried disabling SSL certificate verification in Postman.
Used Different Clients:

Attempted requests via Postman, curl, and browser.
Received Cannot GET /api/user/register in the browser.
Postman and curl both resulted in ECONNRESET.
Curl Command:

Used the following curl command:
sh
Copy code
curl -X POST http://localhost:4000/api/user/register -H “Content-Type: application/json” -d “{“name”: “Anirudh”, “email”: “[email protected]”, “password”: “password”}”
Questions:

What could be causing the Cannot POST /api/user/register error?
Are there any specific configurations I might be missing in my setup?
Could the issue be related to the Windows firewall or network settings?
Any other suggestions to troubleshoot and resolve this issue?
Console Logs:

Server is running on http://localhost:4000
database connected
Received registration request { email: ‘[email protected]’, name: ‘Anirudh’, password: ‘password’ }
Any help or pointers would be greatly appreciated!
