So, you’re browsing through the web and you’re about to watch your favourite YouTube channel.
Just as you’re about to load the website, you see an error which pops up in Chrome that says:
“This site can’t be reached.
- Checking the connection
- Checking the proxy and the firewall
When you try and refresh the page to see if this was a mistake, you still get the dumb error. This can be an annoying situation especially if it’s been happening for a long time.
The Reason You’re Seeing the Error in Chrome
The reason you’re seeing this is mainly because of your proxy server settings.
A proxy server acts as a gateway between your local network and the internet.
They provide a higher level of performance and security while you’re browsing the web.
If there’s an issue with your proxy server settings, it means that you’ll need to check the proxy server settings.
1. Check Proxy Server Settings
Since Chrome lists this as one of the first things to do, it makes perfect sense to try to check your proxy server settings first.
This may sound confusing and complicating but it actually isn’t.
To check the proxy server settings:
- Go to the control panel
- Click on Network and internet
- Click on Internet options
- Click on the connections tab
- Click LAN settings
- Under proxy server, check the first box
When you check this first box, it basically automatically detects settings that have overridden the manual settings.
This may be what’s preventing you from visiting web pages.
After you’ve done this, you should refresh the page and see if it works.
If it doesn’t, go to the next step.
2. Disconnect from your Network
The next thing you need to do is to disconnect from your network then connect again.
Another leading cause of this message is the internet connection.
If there’s an issue with your internet connection, it’s likely that you’ll see this message.
Even if you see the Wi-Fi icon at the bottom in the panel, this doesn’t mean that your internet connection is good.
You may have incredibly slow internet speeds and the Wi-Fi icon may still look fine.
You’ll need to fully restart your connection from the panel below to see if this is causing the problem.
To restart your connection:
- Click on the Wi-Fi icon below
- Click Disconnect
- Click connect
After you’ve done this, you need to try and reload the page.
If you reload the page and it’s working, it looks like your internet was just being slow.
If this step didn’t work, go to the next step.
3. Flush your DNS
The next thing you need to do is flush your DNS.
Your DNS is responsible for returning the IP address of the web server to the domain your trying to visit.
If there’s an issue with your DNS, you won’t be able to visit domains because the IP address that’s hosting the domain won’t be returned when the domain is searched.
To flush the DNS:
- Click on the search
- Search for command
- Right click on Command Prompt
- Click run as admin
Copy and paste the following and click enter after pasting each one:
- ipconfig /registerdns
- ipconfig /release
- ipconfig /renew
- netsh winsock reset
Once you’ve flushed the DNS, you need to revisit the webpage and see if it worked.
If this didn’t work, go to the next step.
4. Disable Firewalls
The next thing you need to do is to disable any firewalls that are running.
If you know much about computers, you’ll know that firewalls can cause a lot of issues even though they’re meant to do good things to your computers.
Your firewall is meant to detect viruses on your device.
To turn off your firewall:
- Open the Control Panel
- Click on Windows Firewall
- To turn it off, in the left navigation pane, click on Turn Windows Firewall off
- In the Customise Settings window, select Turn off Windows Firewall and click OK
After you’ve turned off your firewall, you’ll need to go and refresh the page to see if there were any changes.
If this did work, congrats.
