Ensure that the website you’re visiting is up

We understand that this error can occur randomly, even on known stable sites like Youtube or Facebook. However, it still pays to ensure that said sites are actually working at the time you’re troubleshooting the issue. No website runs 100% of the time so  don’t skip this simple step.

The best way to know if the site is working is by using another device, like a different computer or device. For example, if you have a smartphone that has cellular data connection, try to open the site you’re having an issue with to see if it’s not down. If the site works, then go ahead and do the troubleshooting suggestions below.

Solution #1: Check if Firewall or antivirus blocks specific websites

Sometimes, firewalls and security  can become buggy just like any other application so the next good thing to do is check if ERR_CONNECTION_REFUSED error is due to your machine’s firewall and/or security app. Try to turn off your built-in firewall and/or antivirus and see what happens. Though some security software may include their own firewall, we also recommend that you turn off your Windows firewall after turning off your antivirus and third party firewall. To turn off Windows Firewall, follow the steps below:

  1. Click the Start button and search for Control Panel.
  2. Open Control Panel.
  3. In the View by section at the upper right, select Small icons.
  4. Click on Windows Firewall.
  5. Click on the Turn Windows Firewall on or off link on the left side.
  6. Select Turn off Windows Firewall for each network profile (ex: public, private, or domain) you want, and click OK to apply changes.

NOTE: Make sure to turn back on your Firewall and security software after this troubleshooting session.

Solution #2: Check proxy server settings

Most Windows machine owners won’t usually use proxy servers in their day-to-day computing. Proxy server settings is usually off by default. However, if you’re using a corporate computer or previously used a proxy server to hide your browsing activities, it’s possible that ERR_CONNECTION_REFUSED error you’re experiencing right now is being caused by it. To check, follow these steps:

  1. Click the Start button and search for Control Panel.
  2. Open Control Panel.
  3. In the View by section at the upper right, select Small icons.
  4. Click on Internet Options.
  5. Once Internet Options window opens, click on Connections tab.
  6. Under Local Area Network (LAN) settings section, click on LAN settings button.
  7. Under Proxy server section, make sure that Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections) box is NOT checked.
  8. Click OK to apply changes.
  9. Restart your PC.

Solution #3: Reset TCP/IP

Based on other forums that discussed ERR_CONNECTION_REFUSED error, other users were able to fix the problem by renewing their computer’s TCP/IP. Here’s how to do it:

  1. Press the Windows button to open the Start menu.
  2. Type in Command Prompt.
  3. Righ- click on Command Prompt result.
  4. Select Run as administrator.
  5. Once the Administrator Command Prompt opens, type in ipconfig /renew.
  6. Press the Enter key.
  7. Restart your PC.

Doing the steps above will renew your computer’s IP and its DHCP configuration. It may temporarily disconnect you from your network but your machine will eventually reconnect.  Afterwards, check if you will be able to load the domain you’re having trouble with.

Solution #4: Flush DNS cache

Another good networking tip that you can try in this case is to erase the current Domain Name Server cache your computer is using. Don’t worry, flushing your DNS cache won’t delete user data.  To clear a DNS cache,, here are the steps:

  1. Press the Windows button to open the Start menu.
  2. Type in Command Prompt.
  3. Righ- click on Command Prompt result.
  4. Select Run as administrator.
  5. Once the Administrator Command Prompt opens, type in ipconfig /flushdns.
  6. Restart your PC.
  7. Try to open the domain again.

Solution #5: Restart DNS client

Other users appear to have fixed the problem by restarting the DNS client (service) itself. Restarting this operating system service renews its IP configuration so if the bug lies there, this workaround may help. To restart a DNS service, follow these steps:

  1. Press Windows Key + R.
  2. Type in services.msc in Run dialog box.
  3. Click OK to open Services Manager.
  4. Find the DNS client and right-click it.
  5. Click Restart.
  6. After the process is completed, restart your system and check if the problem is resolved.

Solution #6: Clear browser cache

Outdated or corrupted Chrome browser cache may lead to all sorts of browsing issues so make sure that you refresh it regularly. Ideally, you’re not supposed to clear the browser cache but since you’re having an unexplained issue, it’s worth doing it. Here are the simple steps on how to clear your Chrome browser cache:

  1. Open your Chrome browser.
  2. Copy and paste this to the address bar:  chrome://settings/clearBrowserData
  3. Hit the Enter key.
  4. Choose two options two options Cached Images and Files and Cookies and Other site data.
  5. Under Time range line, click on the drop-down arrow and select All time.
  6. Click the Clear data button.

Solution #7: Reset router

Finally, if all the solutions above won’t help at all, make sure to refresh your router by restarting it. Most wireless routers have their own firewall as well and sometimes, it can get buggy as well. Restarting the router may fix the issue for you. We suggest that you turn the router off and unplug it from the wall outlet for 30 seconds to clear the router’s memory be cleared properly.
