Surely it has happened to you: you open Google Chrome, type in the address of a page you urgently need to visit and suddenly the dreaded message appears "This site cannot be accessed".
That instant can be desperate, especially if you were working, studying or just wanted to relax while surfing the Internet.
The good news is that this error can be solved and you don't need to be a computer expert to solve it.
In this article I will show you step by step how to solve this problem and recover the smooth navigation on your computer or mobile device.
Why do I get the error "Unable to access this site"? 🔎
The message is usually related to connection problems, browser settings or even DNS server errors.
Sometimes the cause is as simple as an unstable Wi-Fi network, and sometimes it may be due to internal Chrome or operating system settings.
Understanding the source of the problem is key to finding the right solution.
Quick solutions you must try first ⚡
Before moving on to more advanced options, try these basic solutions:
- ✅ Restart the router. It may sound obvious, but a simple reboot corrects connection errors.
- ✅ Open the page in another browser. This way you will know if the failure is in Chrome or in your connection.
- ✅ Clear cache and cookies. Often the stored data causes unnecessary blockages.
- ✅ Try another device on the same network to confirm whether the error is general or specific.
One of the most effective steps to solve this error is to remove the cache and cookies of the browser.
- Open the Chrome menu (the three dots in the upper right corner).
- Select More tools > Clear browsing data.
- Check the boxes for "Cookies and other site data" y "Cached files and images".
- Click on Delete data.
This simple gesture can bring your navigation back to normal.
Verify the DNS configuration 🌍
The DNS (Domain Name System) is the system that translates domain names into IP addresses.
If there is a problem with DNS, Chrome will not know how to reach the website.
To solve it:
- Press Windows + R and write
cmd. - At the command prompt, type:
ipconfig /flushdns - Click Enter.
This will clear the DNS cache and can resolve the failure instantly.
Switch to Google public DNS 📡
If the error persists, you can improve the stability by changing the DNS servers of your connection.
- Open the Control Panel > Network and Internet > Network and Sharing Center.
- Click on your active connection and enter Properties.
- Select Internet Protocol version 4 (TCP/IPv4).
- Check the option Use the following DNS server addresses.
- Enter these values:
- Preferred DNS server: 8.8.8.8
- Alternative DNS server: 8.8.4.4
This small adjustment usually solves the 80% of the cases.
Temporarily disable the antivirus or firewall 🛡️
Sometimes, the antivirus or firewall block access to certain sites.
Try temporarily disabling them and see if Chrome works again.
Remember to re-enable them afterwards to maintain the security of your computer.
Reset Google Chrome settings 🔄
When the above options do not work, resetting Chrome to its original state may be the ultimate solution.
- Open the Chrome menu.
- Go to Configuration > Reset configuration > Restore the original default values of the settings.
- Confirm and restart the browser.
In this way, you will eliminate extensions or configurations that are interfering with the connection.
Verify network connection and wiring 🖧
Although nowadays most of us use Wi-Fi, connection problems can also be caused by damaged cables or a defective network adapter.
Check that everything is properly connected and working.
Update Google Chrome 🔄
Using an outdated version of the browser may cause compatibility errors.
To update it:
- Click on the three dots in the menu.
- Select Help > Google Chrome information.
- If an update is available, it will be downloaded automatically.
