How To Fix A Err_Connection_Refused Error In Google Chrome

Google Chrome displays an ERR_CONNECTION_REFUSED error message when a website fails to respond to a request to connect to it. Although that sounds like an issue on the server-side (and it very well could be), many reasons—such as an obsolete DNS cache and conflicting network settings—can also trigger the error.

If reloading the website, relaunching Chrome, or restarting your PC or Mac didn’t help, then working your way through the list of troubleshooting tips below should sort things out.

Table of Contents

1. Check Website Status

To rule out potential server-side issues, you must check the website’s status by running its URL through an online tool such as Downdetector or CurrentlyDown. 

If you receive a message indicating that the site is down for everyone, you must wait it out until the website comes back online. You could also notify the webmaster via email or social media to speed things up.

2. Clear DNS Cache

If the site is up for everyone else but not you, an obsolete DNS (Domain Name System) cache is the likely reason behind the ERR_CONNECTION_REFUSED error. Deleting it should force your computer to update the website’s IP (Internet Protocol) address, which may have changed since the last time you accessed it.

Clear DNS Cache in Windows

1. Press Windows + X to open the Power User Menu. Then, select Windows PowerShell (Admin).

2. Type the following into an elevated Windows PowerShell console:


3. Press Enter and exit Windows PowerShell.

Clear DNS Cache in macOS

1. Press Command + Space to open Spotlight Search. Then, type terminal and press Enter.

2. Copy and paste the following command into the Terminal console and press Enter:

sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder

3. Type in your administrator password and press Enter again to execute the command. Follow by exiting Terminal.

3. Change DNS Servers

Spotty and unreliable DNS servers on the PC and Mac can also prevent Chrome from connecting to specific websites. To rule that out, you must switch to a popular public DNS service such as Google DNS.

Change DNS Servers on Windows

1. Open the Start menu and select Settings.

2. Select Network & Internet.

3. Switch to the Wi-Fi or Ethernet side-tabs.

4. Pick your network connection.

5. Under IP Settings, select Edit.

6. Set Edit IP Settings to Manual and turn on the switch under iPv4.

7. Type the following DNS addresses into the Preferred DNS and Alternate DNS fields:

8. Select Save.

Change DNS Servers on macOS

1. Open the Apple menu and select System Preferences.

2. Select Network.

3. Pick Wi-Fi or Ethernet and select Advanced.

4. Switch to the DNS tab.

5. Add the following DNS servers:

6. Select OK, then Apply.

4. Clear Chrome Cache

An outdated Chrome cache can lead to data mismatches and, subsequently, site loading issues. If the DNS-related fixes didn’t help, you should try clearing it.

Start by deleting the cache just for the site that displays the ERR_CONNECTION_REFUSED error. In case that doesn’t fix the problem or the same error keeps appearing on multiple websites, go ahead and clear the entire browser cache.

Clear Cache for One Site Only

1. Try loading the website. Then, select the Info icon on the address bar.

2. Select Site settings.

3. Select Clear data.

Clear the Full Browser Cache

2. Switch to the Advanced tab. 

3. Set Time range to All time.

4. Check the boxes next to Cookies and other site data and Cached images and files.

5. Select Clear data.

5. Renew DHCP Lease

If none of the fixes above helped, you must renew the DHCP (Dynamic Host Configuration Protocol) lease on your computer. That involves requesting a fresh IP address from the network’s router.

Renew DHCP Lease on Windows

1. Open an elevated Windows PowerShell console.

2. Run the two commands below in the following order:

ipconfig /release

ipconfig /renew

3. Exit Windows PowerShell.

Renew DHCP Lease on Mac

1. Open the Apple menu and select System Preferences.

2. Select Network.

3. Pick Wi-Fi or Ethernet and select Advanced.

4. Switch to the TCP/IP tab.

5. Select Renew DHCP Lease.

6. Select OK.

7. Exit System Preferences.

6. Disable VPN and Proxy Servers

Do you use a VPN (Virtual Private Network) on your PC or Mac? It’s the best way to protect your privacy on the internet. However, VPNs also introduce connectivity-related issues, so disable yours and check if that helps.

Additionally, you should disable any active proxy servers. Here’s how to check for and deactivate proxy servers on the PC and Mac.

7. Add Chrome to Firewall

Another ERR_CONNECTION_REFUSED error-related fix involves adding Google Chrome as an exception to the Windows or the macOS firewall—if it already isn’t.

Add Chrome to Firewall on Windows

1. Open the Settings app.

2. Select Update & Security.

3. Switch to the Windows Security side-tab.

4. Select Firewall & network protection.

5. Select Allow an app through firewall.

6. If you don’t see Google Chrome listed within the list of apps, select Change settings, followed by Allow another app.

7. Select Browse and choose the chúng tôi file from the following location:

C:Program FilesGoogleChromeApplication

8. Select Add, then OK.

Add Chrome to Firewall on macOS

1. Open System Preferences.

2. Select Security & Privacy.

3. Switch to the Firewall tab. 

5. Select the Plus icon and pick Google Chrome.

6. Select Add, then OK.

8. Check Chrome Extensions

Extensions help improve Chrome, but unoptimized add-ons also introduce connectivity issues. Identify and remove them.

1. Open the Chrome menu. Then, point to More tools and select Extensions. 

2. Deactivate each active extension.

3. If that ends up fixing the ERR_CONNECTION_REFUSED error, reactivate the extensions one at a time until you come across the add-on causing the issue. Once you do, remove it and look for an alternative extension.

9. Run Cleanup Tool (Windows Only)

The PC version of Google Chrome comes with a built-in tool that can identify and remove malicious extensions, browser hijackers, and other harmful software from your computer. If Chrome shows signs of performance-related issues besides displaying the ERR_CONNECTION_REFUSED message, you should try using it.

1. Open the Chrome menu and select Settings.

That should prompt Chrome to scan for and remove harmful software from your computer.

10. Reset Chrome

Do you still keep running into the ERR_CONNECTION_REFUSED error in Chrome? Resetting the web browser should revert any corrupt configurations preventing it from working correctly.

1. Open the Chrome menu and select Settings.

Once Chrome finishes resetting itself, sign into the browser and re-activate any extensions. Then, try using it. You likely won’t encounter the error again.

3. Uninstall dodgy programs

Try uninstalling some suspicious programs that you don’t recall installing, one of which might be the culprit behind the Google Chrome Critical Error red screen.

4. Clear Chrome’s cache

The Chrome Critical Error red screen will have some cache data.

Fix Err Bad Ssl Client Auth Cert Error For Google Chrome

Google Chrome web browser checks the SSL Security Certificate of the web page that the user is trying to access. If it is unable to, then one error related to SSL Certificates which a user may face while browsing with Chrome is ERR BAD SSL CLIENT AUTH CERT. This can be caused due to many factors like the computer’s Time and Date is out of sync, Cached Data is corrupt, third-party software installed on the computer is blocking the site, etc.


The cause could also be at the website’s end. The server is rejecting the certificate the client website is sending. It could have expired, or the server may not trust its issuer. Nevertheless, there are a few things you could try at your end. To fix this error, we will be taking a look at the following methods-

Update Google Chrome.

Sync Date and Time.

Clearing browser data.

Checking and fixing any third-party software conflicts.

Change TLS/SSL3 and QUIC settings.

1] Update Google Chrome

You can try to get the latest version of Google Chrome and have it installed on your computer and check if that fixes your issue.

2] Sync Date and Time

Wrong Date and Time settings on Windows 10 can also cause conflicts like this. It* is due to the incompatibility between the SSL Certificate validation date and the System Clock. Hence, the user should sync their System Clock.

All you need to make sure is that the Time Zone setting on the same page is correct.

3] Clear browser data

There are high chances that some browser data is conflicting with the loading of the website. It might be a very basic fix, but in this case, it can be proved a highly reliable one.

For this, start by opening Google Chrome. Now hit the CTRL + H button combination on your keyboard.

Restart your browser and check if your error is fixed or not.

4] Check and fix any third-party software conflicts

Third-party internet protection software like Antivirus can also be a cause for this error. Due to some reason, they might be detecting the web page to be malicious or with less credibility. And hence, this might be blocking the web page on your web browser. So, to fix that, I would suggest you see if any third-party software like VPN, Security software, or an add-on may be interfering and turn it off. You could open your antivirus software and temporarily disable web protection and see if that helps.

5] Change TLS/SSL3 and QUIC settings

As a temporary measure, you may try disabling TLS1.1 & TLS1.2 and enabling SSL2 & SSL3 and see if that helps.

Follow the protocol fixes for SSL3/TLS and QUIC, which are some of the reasons to cause the error. If your antivirus or security software offers this setting, you may disable “SSL/TLS” protocol filtering and see.

How do I import client certificates to Chrome? Why does it say this site can’t provide a secure connection?

If the site cannot offer an SSL certificate, its certificate has expired or doesn’t offer an SSL certificate for HTTPS-Complaint. While you cannot do much here, the browser provides the option to access it by accepting the risk. So make sure you only do it with a website you trust enough, even though it’s not recommended.

Are these fixes effective?
