ERR_CONNECTION_REFUSED: Definition and How to Solve It

In today's digital age, where online presence is crucial for businesses and individuals, encountering technical errors such as ERR_CONNECTION_REFUSED can significantly impact website performance and user experience.

This frustrating error occurs when a browser attempts to establish a connection with a website but is refused, leaving users unable to access the desired content. 

Moreover, it not only disrupts the browsing experience, but can also badly impact website visibility, engagement, and ultimately, business success. 

Understanding the causes of this error message is crucial for website owners seeking to maintain a seamless online presence and optimise their digital performance.

In this article, we'll take an in-depth look at the definition, causes, and how to solve ERR_CONNECTION_REFUSED.

What Is ERR_CONNECTION_REFUSED?

The ERR_CONNECTION_REFUSED error indicates a connection issue where the browser is unable to establish a connection with the intended website. This problem is commonly encountered in Google Chrome and can occur due to a poor internet connection. 

In HTTP status codes, it is represented as HTTP 111, which signifies that the server has received a connection request but chose to reject it. 

This error is usually followed by a message such as "This site can't be reached" on the browser screen. 

Although it occurs frequently on the internet, this error message can be frustrating for users, as it prevents access to desired web pages.

Causes of ERR_CONNECTION_REFUSED 

As we've mentioned before, the ERR_CONNECTION_REFUSED error in Google Chrome can come from a variety of sources beyond a bad internet connection. 

Although connectivity issues are a common cause, other factors can contribute to this error, including:

• Expired cache and cookies in your browser.
• Problems with your computer or router.
• Connectivity issues within your network.
• Firewall or antivirus software blocking access.
• Proxy server or VPN network settings.
• Expired DNS cache or DNS server issues.
• Browser extensions blocking the connection.
• Corrupted Google Chrome browser installation.
• Hostname settings in the “hosts” file.
• Problems with Chrome Extensions.
• Interference from antivirus software or firewalls.
• Incorrect internet settings.
• Using an outdated browser version.

How to Solve ERR_CONNECTION_REFUSED 

Identifying and addressing these potential causes can help resolve this error message and restore normal browsing functionality. Here are some tips on how to solve the ERR_CONNECTION_REFUSED:

1. Clear Cookies and Cache of Your Browser

Even though your browser's cache and cookies are designed to improve website loading speed, they can sometimes become outdated or corrupted, resulting in this connection error message. 

To resolve this issue, you should regularly clear your browser's cache and cookies. The process for doing this may be different depending on your device or browser. 

2. Check Your Internet Connection

If you see the connection error message, it may indicate a problem with your internet connection. 

One troubleshooting step is to switch to a different network, such as mobile data if you're using Wi-Fi. If the error is resolved on an alternate network, this indicates that the problem lies with your original internet connection. 

In such cases, contacting your Internet Service Provider (ISP) for assistance may help resolve the underlying issue. 

Additionally, checking the connection ERR_CONNECTION_REFUSED by restarting the router or trying alternative networks can help diagnose and resolve connectivity issues effectively.

3. Disable Your Firewall or Antivirus Program

Antivirus programs and firewalls play an important role in protecting against online threats, but sometimes they can be too strict and mistakenly block access to legitimate websites, resulting in this connection error message in Chrome. 

To determine if these programs are the cause of the problem, you can disable them temporarily and try accessing the website again. 

If it works, this indicates that antivirus software or a firewall is blocking the connection. In that case, you should consider adding the website to your security software's whitelist or adjusting its settings to allow access. 

After it has been resolved, reactivate the antivirus program and firewall to ensure ongoing protection against real threats while browsing the internet.

4. Flush Your DNS Cache

The DNS cache stored in your operating system serves to speed up website resolution by reducing DNS lookup time, but sometimes the DNS cache can become outdated and conflict with access to certain websites. 

This mismatch can result in this error message, especially if the website's IP address has changed while the DNS cache stores outdated entries. 

To resolve this issue, you should clear the DNS cache in your operating system. The specific process for clearing the DNS cache depends on your operating system.

5. Change Your DNS Server

Although your Internet Service Provider (ISP) usually assigns DNS servers automatically, problems with these servers can cause this connection error message in your browser. 

By changing your DNS servers to reliable alternatives, such as free public DNS servers from Google or Cloudflare, you can troubleshoot and potentially resolve connectivity issues. 

This process involves switching to a different DNS server address to determine if it can resolve the issue. 

Overall, using a more stable and responsive DNS server, you can reduce connection errors and ensure a smoother browsing experience.
