How to fix ERR_CONNECTION_REFUSED in Chrome

ERR_CONNECTION_REFUSED is one of the common network errors in Chrome browsers and usually means that the browser cannot connect to the target server. There may be many reasons for this problem, such as local network settings, website server problems, or cache exceptions in the browser itself. Here are some common and practical solutions.

How to fix ERR_CONNECTION_REFUSED in Chrome

1. Check whether the network connection is normal

This is the most basic but also the easiest to ignore. First, confirm whether your device can access other websites normally.

How to fix ERR_CONNECTION_REFUSED in Chrome
  • If it is Wi-Fi, try disconnecting or restarting the router.
  • If you are using a wired connection, check whether the network cable is plugged in properly.
  • Run ping www.google.com (Windows) or ping www.apple.com (Mac) on your computer to see if there is a response.

If other websites cannot be opened, the problem is most likely in the network itself, not the browser.


2. Replace DNS or refresh the DNS cache

Sometimes there is a problem with the DNS that comes with the system, which will cause the resolution to fail, resulting in the connection being denied.

How to fix ERR_CONNECTION_REFUSED in Chrome

How to replace DNS:

  • Using Google Public DNS: 8.8.8.8 and 8.8.4.4
  • or Cloudflare 1.1.1.1

How to refresh the DNS cache:

  • Windows: Open the command prompt and enter ipconfig /flushdns
  • Mac: Enter sudo killall -HUP mDNSResponder

After modifying DNS, you can try to see if you can open the web page. If it doesn’t work, continue to the next step.


3. Clear browser cache and cookies

Excessive Chrome cache or corrupt cookies can also cause connection exceptions.

The operation steps are as follows:

  • Open Chrome Settings → Privacy and Security → Clear browsing data
  • Select "All Times" in the time range
  • Check "Cookies and other website data", "Cached pictures and files"
  • Click "Clear Data"

After cleaning, refresh the page to see if it returns to normal.


4. Turn off proxy settings or firewall software

Sometimes you may enable local proxy or install certain security software (such as antivirus software, firewalls), which may intercept normal network requests.

How to close the proxy:

  • Windows: Settings → Network and Internet → Proxy → Turn off "Use Proxy Server"
  • Mac: System Settings → Network → Advanced → Agent → Uncheck the relevant options

Turn off firewall/antivirus software testing:

  • Temporarily disable third-party firewalls or antivirus software (do not close for a long time)
  • Try to reload the page

If you are not sure if it is a problem with these programs, you can troubleshoot them one by one.


5. Reset Chrome settings or use Invisible Mode

Chrome's extensions or custom settings can sometimes interfere with network connections.

Test using incognito mode:

  • Open Chrome Invisible Window (Shortcut Key Ctrl Shift N)
  • Enter the URL to see if it can be accessed normally

Reset browser settings:

  • Chrome Settings → Reset Settings → Restore to original default settings

This operation will not delete bookmarks and passwords, but will clear some advanced settings.


Basically, these common inspection methods. Some problems may require a combination of several methods to solve, such as clearing the cache first and then turning off the firewall. Although it seems a bit too many, most of the operations are not complicated and are just easy to be ignored.
