To test it, you have two ways of analyzing the website status:

  • If the website you are trying to open shows the connection error, try to access other sites. If other websites open without err_connection_refused error, this means your desired page is the actual problem of causing a connection
  • The second way to check is by using the tool “Down for Everyone Or just me.” This web tool will provide you overall result regarding whether your desire website is down or not. You can check it by typing the web address in the non-functioning section and click “or just me?”

3-  Clean Browser Cache

For the sake of so-called personalization features, Google Chrome collects many data in the cache. The data collect by Chrome includes, visited domains, static content, domains, and it goes on!

These data cache becomes one of the reasons for err_connection_refused error because they get outdated.

Moreover, due to no longer match between the target site and data cache, your browser shows connection error. To resolve this issue in Chrome is by cleaning the browser cache.

There are two ways to clear the browser cache in chrome. To do so:

Method 1: First open the Chrome browser > Now click on the “three dots” icon on the top right corner of the screen > the menu bar will appear on the screen > select “More tools” option > now select “delete browser data” and wait for the process.

Method 2: In the address bar type   “chrome://settings/clearBrowserData” > it will direct you to clear browser cache option.

In both scenarios, you can directly to clean browser cache option. After clearing on the clear browser data > select “All Time” data from Time range slot and put a check on all the mentioned below options > now click on “clear data” option and wait for the process.

4-  Recheck Your Proxy Settings

Online privacy is one of the most crucial aspects since our world is now becoming data-driven society. Therefore, to maintain online privacy, users use a different kind of security tools to protect their data.

Moreover, the recent incidents of online privacy invasions increase the use of VPN software that uses private servers to encrypt your online data by using a high level of encryption standards and protocols.

Due to using private servers through VPN, sometimes it causes a problem that causes a problem in the proxy. And this leads to “err_connection_refused” error to appear on your device screen while browsing.

If you receive a message like the Chrome 102 error, it is recommended to check your own proxy settings and delete registered servers in case of doubt.

For this purpose, Chrome even has its own entry in the browser options, which saves you having to search for the corresponding menu in your system settings.

To do so, open the Chromes settings by entering the “Chrome://settings/” in the search bar > now from the list of options select “advanced” option > list of options will appear on the screen, now select “System” > click on “Open Proxy Settings” and check whether your connection is working fine or not.


For Windows users, Windows users then click on “LAN settings” and uncheck (if necessary) “use a proxy server for LAN.”

Mac users immediately land in the appropriate menu and only have to uncheck all selectable proxy protocols.

5-  Disable Firewall and Antivirus

Firewalls and antivirus are also caused “Err_connection_refused” error to protect your system from malicious malware and viruses. You might use anti malware software like Malwarebytes. Make sure you have read that Malwarebytes is safe to use on your PC or Mac.

However, sometimes this security software unblocks websites without any justifiable reason. Therefore, it creates a problem to establish a connection between your server and site.

So to check whether the err connection problem occurs due to firewall or antivirus, disable them temporarily.

If the connection problem resolves after disabling firewall and antivirus from your device, then look for the appropriate changes that will solve the connection issue.

Moreover, also do not need to compromise on your system’s security at the same time. Or switch to other security tools that are compatible with your internet connection.

6-  Clear DNS Cache

I am little concern about the information regarding that your device also collects data related to your browsing behavior.

Similar to browser cache, a DNS cache collects all your browsing history and online activities to upload those websites, which you use on a regular basis.

This DNS cache makes the process speedy by eliminating the need to contact a DNS server repeatedly.

However, this process is not fruitful in every case. Like for example if any query no longer matches the recent version of the site, it creates the connection problem like ERR_CONNECTION_REFUSED ERROR.

So, to resolve this issue just clean DNS cache of your device. For Windows users, to do so:

Open the command prompt > Now in the command prompt type “ipconfig/flushdns” and press enter key.
