When browsing the internet, you may sometimes encounter errors that prevent you from accessing a specific website or web page. Due to such errors, you will have a less enjoyable experience using the internet. Among all, one common error users may encounter while using Google Chrome is ERR_CONNECTION_REFUSED or ERR CONNECTION REFUSED .

This error is pretty frustrating and indicates that something major has gone wrong on the client side. It does not indicate any specific cause, like other errors. As a result, novices panic when they receive such errors. However, addressing and fixing ERR_CONNECTION_REFUSED is quite easy.

In this article, we'll discuss the ERR_CONNECTION_REFUSED error, its causes, and potential ways to fix it, allowing you to browse the internet seamlessly using Google Chrome.

When you access a specific website through Google Chrome, but the browser cannot establish a connection or refuses to connect, you encounter ERR_CONNECTION_REFUSED. Hence, we can say that it is a connection error. It is a client-side error, and a poor internet connection is a major possibility for the occurrence of this error.

This error is also encountered in browsers like Mozilla Firefox, Microsoft Edge, and Safari. Let us see what the ERR_CONNECTION_REFUSED error looks like in other browsers.

Error Causes

●     Poor internet connection

●     Faulty Chrome extensions

●     Cache issues

●     The interference of firewall, antivirus, or VPN (Virtual Private Network)

You encounter this issue in Google Chrome due to common reasons, such as a poor internet connection. Well, there might be other causes, as follows:

  • Issues with browser cookies
  • DNS cache issues
  • Chrome extension issues
  • Incorrect internet settings
  • Antivirus, firewall, or VPN interference
  • Outdated browser version

Sometimes, the ERR_CONNECTION_REFUSED error isn't caused by anything on your computer or network. The website itself might be experiencing problems. Here are a few common server-side causes:

  • Incorrect Firewall Settings: The website's server may have firewall rules that are accidentally blocking your connection attempts.
  • Server Overloads: If the website is experiencing high traffic, the server might become overwhelmed and refuse new connections.
  • Website Downtime: The website might be down for maintenance or due to unexpected technical problems.

Fixing this error is pretty easy if you know the exact cause. However, due to the unknown cause, you might need to try out a few things to resolve the error.

The following are some simple and effective ways to fix the ERR_CONNECTION_REFUSED error

1. Check the Website Status 

Before considering other troubleshooting methods, check the status of the website you want to visit. Sometimes problems with your internet connection are not the root cause of the error. Instead, it may be a result of the website server issue.

The best method to rule out the possibility that the website server is the issue is to try to access the website from another browser or internet connection. If the problem exists, this means there are some issues on the server side. But if you have this problem only in your Chrome browser, you should follow the next steps to discover and solve the problem.

Further, check whether the website is not accessible only to you or other users. To check this, you can use Down For Everyone Or Just Me. Enter the website URL and click on the ‘or just me?’ button.

It provides the website's status – online (up) and offline (down). If the website is down, you can simply wait to get it fixed by the owners. If the website is online and you can’t access it, it indicates a problem with your browser, internet connection, etc. In this case, you can follow the below troubleshooting steps.

2. Check Proxy Settings

Many users leverage proxy servers to enhance data security by using a different IP address when going online. This can result in the ERR_CONNECTION_REFUSED error. Proxy servers are useful as they help you filter server communications and cache data, and keep your IP address private.

Usually, the error appears when a website server rejects the IP address linked to the proxy server, denying you the connection to the website.

This means checking your proxy settings if you get the error is a worthwhile shot, as there is a high possibility the proxy is incorrectly configured or is offline.

If you are browsing on Chrome, you can find proxy settings in the Chrome browser. You need to follow the below-listed steps:

Step 1: Open Chromes settings menu 

Evaluate Your Proxy Settings

Step 2: Click "Advanced" at the bottom of your screen or type "System" in the search field.

Step 6: Check if you still get the error when accessing the website. 

If the err connection refused error does not clear, proceed to the next step.

3. Restart Your Router

If the cause of the error is internet-related problems, restarting your router will help. A hard reboot or switching your router on and off can fix internet-related issues. However, it is still important to remember that this only sometimes fixes internet-related issues.

This is a good starting point before you engage your internet service provider to confirm issues with your connection.

Once the router is up and running, check if you still get the error on your browser. If unresolved, there is likely another cause.

4. Check Your Router and Network Settings

If restarting your router didn't help, there might be a more specific configuration issue preventing connections. Check the following:

  • Firewall Settings: Your router might have a firewall that's interfering with website connections. Consult your router's documentation on how to check and adjust firewall rules.
  • LAN Settings: Ensure that your computer's local network settings are correct. Incorrect proxy settings or other misconfigurations within your local network setup can cause connection problems.

To fully troubleshoot network-related issues, it's helpful to have a basic understanding of how local area networks (LANs) function. You can find a good explanation on the MonoVM blog.

5. Adjust Your DNS Address

An outdated DNS cache entry and the DNS address can cause ERR_CONNECTION_REFUSED Chrome. The error usually occurs when the DNS address is offline or overloaded.

Usually, your internet service provider automatically assigns the DNS server address, but you can still change it if necessary. The process of changing your DNS address depends on your computer’s operating system.

Step 3: You will get a list of extensions on your browser. Click the "Remove" button on extensions that you don't need.

Step 4: Try browsing again to see if you still get the error.

8. Disable Firewall and Antivirus Software Temporarily

A firewall and antivirus software protect computers from viruses and other online threats. They regularly scan your files and network for any malicious or suspicious activities and block them from affecting your computer system.

In addition, these programs also block unsafe websites. Hence, if a website you try to access is not secure, firewall and antivirus software block it and prevent you from accessing it.

In this case, disabling the firewall and antivirus software temporarily would be a great solution. If you use your system’s default firewall or antivirus, you can disable it from your system settings.

However, if you leverage any third-party, specialized software, follow the software-specific steps to disable the firewall and antivirus. Ensure to go through software documentation before implementing any step.

Note: Disable firewall and antivirus software temporarily. Otherwise, you may be at great risk of infecting your computer with viruses and malware.

9. Clear Your DNS Cache

Like a browser creates a cache, our computer’s operating system does the same. The DNS cache comprises temporary entries for all pages you visit within our browser. These entries store the domain names and addresses of all websites you access or visit.

The DNS cache serves the same purpose as the browser cache, i.e., it speeds up the loading process. It does not have to contact the site’s DNS server frequently. If the entry in the DNS cache is too old and does not match the website’s current version, you receive the error ERR_CONNECTION_REFUSED.

In such a scenario, flushing the DNS cache is the solution. It is straightforward to flush the DNS cache.

Flush the DNS Cache on Windows

Step 1: Go to the “Command Prompt” from the Start Menu.

Step 2: In the command prompt, execute the following command:

ipconfig /flushdns

The above command flushes all the DNS resolver cache successfully.

Check out the detailed guide to flush DNS on Windows here.

Flush the DNS Cache on macOS

Step 1: Open “Terminal” from the Spotlight Search.

Step 2: Type the following command in Terminal and hit “return”.

sudo killall -HUP mDNSResponder && echo macOS DNS Cache Reset

This will clear the DNS cache.

After this, try accessing the website and check if the error has been resolved.

10. Troubleshoot the Internet Connection

If the internet connection is a problem causing the ERR_CONNECTION_REFUSED error, it becomes essential to troubleshoot the internet connection. Windows and macOS systems have built-in troubleshooting tools to identify and fix internet issues.

Troubleshoot the Internet Connection on Windows

Step 1: Go to “Settings” from the Start menu or simultaneously press the keys – Windows key + I –.

Step 2: Choose “Network & Internet”, and click “Troubleshoot”.

Step 3: Select the network adapter you want to troubleshoot and click “Next”.

Step 4: Wait for a while until the system analyzes issues. If issues are found, implement the suggested fixes.

Step 5: Once done, reboot the computer and check whether the error resolves.

Troubleshoot the Internet Connection on macOS

Step 1: Disconnect all external devices from your MacBook except a keyboard and monitor.

Step 2: Shut down the system.

Step 3: Turn the system on and press and hold the key – D.

Step 4: Next, choose the preferred language.

Step 5: Wait until Apple Diagnostics is running.

Step 6: If the system identifies any errors, it suggests possible fixes.

Implement the fixes and reboot the system.

11. Deactivate VPN

VPN stands for Virtual Private Network. It is among the security solutions that mask your original IP address and keep you anonymous while using the internet. This prevents hackers, third parties, and Internet service providers from peeking into your browsing history and Internet activities.

A VPN can interfere with the Internet connection and result in the ERR_CONNECTION_REFUSED error. Deactivating a VPN can help you get rid of this error.

It is better to review a VPN service's software documentation or guidelines and deactivate it temporarily. Once your error resolves, ensure to connect back to the VPN service to surf the internet anonymously.

12. Reinstall Chrome

The last option you can try is to uninstall the Chrome browser. Like other applications, Chrome also cannot be 100% bug-free. Your browser installation may contain issues if you haven’t updated it for a long time. Another reason for the error may be the browser and operating system issues.

In such cases, uninstalling and reinstalling Chrome can be a great solution. Remove the current Chrome installation and install the latest version from its official website.

However, before you uninstall Chrome, try resetting it to bring back its original settings.

Here is how to reset Google Chrome:

Step 1: Open Chrome on your system.

Step 2: Click on the three dots in the top right corner.

Step 3: Choose “Settings” and click “Reset Settings”.

Step 4: Next, choose “Restore settings to their original defaults” and click “Reset Settings”.

If the previous solutions haven't resolved the ERR_CONNECTION_REFUSED error, here are some more in-depth troubleshooting steps:

  • Checking the Windows Hosts File: The hosts file on your computer can override DNS settings. Incorrect entries could be redirecting you away from the website you're trying to access. [Provide a link or brief instructions on how to check/edit the hosts file].
  • Temporarily Disabling IPv6: In rare cases, incompatibilities with IPv6 can lead to connection problems. [Provide instructions on how to temporarily disable IPv6 on Windows].
  • Resetting Network Settings: If there's a deeper network configuration issue, resetting your network settings to defaults might help. [Provide instructions or a link to instructions for resetting network settings on Windows].

Caution: These steps involve modifying system settings. Before proceeding, make sure you understand the potential consequences or create a backup of your current settings.

If you've exhausted all the troubleshooting options and still encounter the ERR_CONNECTION_REFUSED error, it's time to seek additional help:

  • Contact Your ISP: Your Internet Service Provider might be able to identify any network-wide issues affecting connections to specific websites.
  • Contact the Website Administrators: If you're certain the issue is not on your end, reach out to the website owners to report the problem. They might be able to diagnose and resolve server-side issues.

These were some effective ways to fix the ERR_CONNECTION_REFUSED error. It is the connection error typically occurring in Google Chrome. Client-side issues, such as poor internet connection, Chrome extension issues, antivirus and firewall interference, etc, primarily cause it.

Though connection errors seem daunting, they can be fixed. So, while fixing such errors, you must try out all options available patiently.
