Struggling with *"localhost refused to connect"* errors while running a server in VSCode? This video walks you through step-by-step solutions to resolve connection issues and get your local development environment running smoothly.

*What we cover:*
*Port Conflicts:* Identifying and killing processes using the same port (e.g., `http://localhost:3000`)
*Server Configuration:* Ensuring your dev server (Node.js, React, Python, etc.) is running and bound to `0.0.0.0` or `localhost`
*Firewall/Antivirus:* Allowing VSCode and local servers through security software
*Proxy Settings:* Adjusting network configurations for corporate/vpn environments
*Browser & Cache Issues:* Clearing browser data or testing with incognito mode

*Advanced fixes:*
Resetting hosts file entries (`C:\Windows\System32\drivers\etc\hosts`)
Using `netsh` (Windows) or `lsof` (Mac/Linux) to manage ports

*Pro tips:*
Always check if your server is actually running in the terminal
Use `http://127.0.0.1` instead of `localhost` to bypass DNS issues
