Chrome ERR_CONNECTION_REFUSED

Chrome ERR_CONNECTION_REFUSED means the website server actively refused the connection, usually because no service is running on that port. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Chrome cannot establish a connection to the server. Server is reachable but nothing is listening on the port. Different from timeout (ERR_CONNECTION_TIMED_OUT). Common with localhost development servers. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Web server is not running or has crashed. Firewall blocking the connection port. Wrong port number in the URL. Server configured to reject connections from your IP. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Check if the website is down using isitdownrightnow.com. Flush DNS cache: chrome://net-internals/#dns. Disable proxy settings: Settings > System > Proxy. Try accessing from a different network. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
