How to fix ERR_CONNECTION_REFUSED on Chrome?

ERR_CONNECTION_REFUSED is a standard error generated by Google Chrome when an unspecified issue prevents access to a website.

Dealing with an error that needs clear clues can be frustrating. This issue has numerous potential causes, but we’ll focus on the most prevalent ones and how to troubleshoot them. Further details are provided below for your reference.

What does ERR_CONNECTION_REFUSED mean?

When Chrome shows you “ERR_CONNECTION_REFUSED,” it means your browser cannot establish a connection to the website you’re trying to reach. It doesn’t pinpoint the exact issue, leaving you stranded with a vague error message.

This error typically occurs when Chrome attempts to connect to a website but encounters resistance. Instead of loading the website, Chrome displays the error message, indicating that something is blocking the connection. The exact cause can vary widely, ranging from issues with your browser settings to network problems or even issues on the website’s server side.

How does ERR_CONNECTION_REFUSED look on different browsers?

You won’t see “ERR_CONNECTION_REFUSED” on other browsers like Firefox or Safari. They have their error messages indicating similar connection problems. Firefox, for instance, might display “Unable to connect,” while Safari might state “Safari Can’t Connect to the Server” without further details.

Error messages across browsers vary significantly, underscoring the importance of understanding each one individually when dealing with errors. Although connection issues remain constant across browsers, individual interpretations of problems may lead to different error messages being displayed by each one.

Common Causes of ERR_CONNECTION_REFUSED Error

The error isn’t always your fault; it can stem from various sources:

• Expired cache and cookies: Your browser stores files (cache and cookies), including cookies that expire or become corrupt, which causes this issue. Clearing both will often help solve the problem by allowing Chrome to make a fresh connection with its intended website.
• Network or device issues: Problems with your computer, router, or network connectivity can also trigger this error. It could be a temporary glitch in your internet connection or a more persistent issue with your network setup.
• Firewall or antivirus software: Overprotective security software might mistakenly block access to the website, interpreting it as a potential security threat. Temporarily turning off these programs can help you determine if they’re causing the connection issue.
• Proxy server or VPN settings: If you use a proxy or VPN, its settings could interfere with website connections. Turning it off temporarily or adjusting its settings may resolve the ERR_CONNECTION_REFUSED error.
• DNS issues: Problems with DNS cache or server settings can also lead to this error. Flushing your DNS cache or switching to a different DNS server (like Google or Cloudflare) can often fix DNS-related connection problems. Additionally, you are using DDoS-protected dedicated server hosting, which adds an extra security layer against DNS attacks.

Identifying the specific cause of the ERR_CONNECTION_REFUSED error is crucial to applying the correct solution. By understanding these familiar sources of the error, you can fix the issue systematically, ensuring a smoother browsing experience. For those using WordPress, opting for the best host for WordPress can significantly reduce the likelihood of encountering such errors due to superior server reliability and support.

Pro Tips:

If you’re encountering the “err_connection_refused” error message in your Chrome browser, there are several potential causes to consider.

• First, check your internet connection. 
• Sometimes, issues with DNS cache or DNS server addresses can cause the err_connection_refused.

Understanding the common causes and applying systematic fixes can ensure a smoother browsing experience.

How to fix the ERR_CONNECTION_REFUSED error

Here’s how to fix this issue:

Quick fixes for visitors

1. Clear browser cache and cookies:

Sometimes, a simple restart of your computer or router can magically solve connection issues. It resets network configurations and clears temporary glitches that may be causing the error.

This often resolves temporary glitches. Your browser stores cached files and cookies to speed up browsing, but these can sometimes become corrupted or outdated, leading to connection errors.

• Desktop browsers: Clear your browser’s cache and cookies.
• Mobile devices: Settings may vary; consult your browser settings or app preferences to clear cache and cookies.

2. Test on other websites:

Check if the error persists on different websites. If it’s site-specific, the problem might lie with the website rather than your browser or network setup.

3. Restart your devices:

Sometimes, a simple restart of your computer or router can magically solve connection issues. It resets network configurations and clears temporary glitches that may be causing the error. To get advanced features, you can choose any suitable managed VPS hosting.

4. Check your internet connection:

Switch networks (from Wi-Fi to mobile data) to see if the error persists. If the error stops on a different network, the problem may be with your Wi-Fi setup or ISP.

5. Disable firewall or antivirus:

Temporarily turn off these programs to see if they’re blocking the connection. They can sometimes be overly cautious and mistakenly block legitimate website access. For additional insights on preventing brute force attacks, check out our article on how to prevent brute force attacks in WordPress.

6. Disable proxy server or VPN:

These might be affecting your connection. Try disabling them to see if it helps. Adjusting proxy or VPN settings may also help resolve connectivity issues. 

Flush DNS cache:

Refresh your DNS cache to ensure it’s not causing the error. DNS caches store recent DNS lookups to speed up browsing, but outdated entries can cause connection problems.

• MacOS: Use Terminal to flush DNS cache (sudo killall -HUP mDNSResponder).
• Windows: Open Command Prompt as admin and enter ipconfig /flushdns.

7. Change DNS server:

Switch to Google or Cloudflare DNS servers to see if it resolves the issue. Sometimes, your ISP’s DNS servers may encounter temporary issues, causing connection errors.

• Google DNS: Primary: 8.8.8.8, Secondary: 8.8.4.4
• Cloudflare DNS: Primary: 1.1.1.1, Secondary: 1.0.0.1

8. Turn off Google Sync:

Sometimes, Chrome sync can cause conflicts with browsing. Temporarily turn off sync to see if it resolves the ERR_CONNECTION_REFUSED error.

• Navigate to Chrome settings, go to “You and Google,” and turn off sync temporarily.

9. Disable browser extensions:

Extensions can sometimes interfere with website connections. Disable them individually to identify if a specific extension is causing the error. You can turn off extensions in Chrome or Opera settings under “More Tools > Extensions.

10. Reinstall Browser:

Reinstalling Chrome or another browser can fix any corrupted installation issues if nothing else works. Uninstall Chrome from your computer and reinstall the latest version.

11. Check hosts file:

Ensure there are correct entries in your host file blocking the website. The host file can override DNS settings and block access to specific websites. A dedicated server performs better and helps prevent issues like the ERR_CONNECTION_REFUSED error.

Fixing ERR_CONNECTION_REFUSED on a WordPress website

If you manage a WordPress site and encounter this error, try these additional steps:

1. Disable plugins:

WordPress plugins can sometimes clash, causing this error. Deactivate each one individually to find the plugin causing the issue.

• Go to Plugins in your WordPress dashboard > Installed Plugins, select all plugins, choose “Deactivate” from the bulk actions menu, and apply

2. Change theme:

Switch to a default theme to see if your current theme is causing the issue. Sometimes, theme updates or conflicts with plugins can lead to connection errors.

• Go to Appearance> Themes in your WordPress dashboard and activate a default theme (like Twenty-One).

3. Increase PHP max_execution_time:

Sometimes, PHP scripts time out, causing this error. Increase the max_execution_time in your PHP settings. Contact your host for help.

• Edit your php.ini file or use PHP settings in your hosting control panel to increase max_execution_time.

4. Contact hosting provider:

If all else fails, your hosting provider may need to check server-side issues. They can verify server logs, firewall settings, or IP blocks causing the connection error.

Conclusion

At first, an ERR_CONNECTION_REFUSED may seem frustrating, but with these troubleshooting steps, you can typically pinpoint and resolve its source.
