How to Fix 'Your Internet Access is Blocked' Error in Chrome on Windows 11/10

As an experienced Windows troubleshooter who's resolved countless browser glitches, I know how frustrating it is when Google Chrome suddenly blocks your internet access on Windows 11 or 10. You might see the ERR_NETWORK_ACCESS_DENIED error, preventing websites from loading. Below, I'll explain the common causes and proven fixes based on real-world testing.

Why Is Internet Access Blocked in Google Chrome?

This error can disrupt your workflow, but it's often fixable. Here are the top culprits:

• Restricted networks: Workplaces, schools, or public Wi-Fi may block sites. Contact your network admin for access.
• Malware or viruses: Infections from malicious files can alter network settings, triggering the block.
• Network driver issues: Outdated or faulty drivers can interfere with Chrome's connectivity.
• Firewall blocks: Antivirus firewalls often flag suspicious activity, halting access.

How to Fix 'Internet Access is Blocked' in Chrome

Start with these Chrome-specific solutions, tested on Windows 11 and 10. We'll go step-by-step.

1. Clear cache
2. Disable third-party extensions
3. Delete Chrome profile
4. Adjust firewall settings
5. Reset Chrome

1. Clear Cache and Browsing Data

Corrupted cache or cookies can conflict with site IPs. Press Ctrl + H to open History, then click Clear browsing data.

Select All time, check Browsing history, Cookies, and Cached images and files, then hit Clear data. Restart Chrome—this fixes many cases.

2. Disable Third-Party Extensions

Problematic extensions can trigger firewalls. Click the three dots in Chrome's top-right, go to More tools > Extensions.

Remove or toggle off unnecessary ones. Test browsing afterward.

3. Delete Chrome Profile

Corrupt profiles cause issues. First, end chrome.exe in Task Manager. Or, after restarting PC:

1. Press Windows + R to open Run.

2. Enter

%LOCALAPPDATA%\Google\Chrome\User Data\

Rename Default to Default.old. Chrome will create a fresh profile.

4. Adjust Firewall Settings

If your antivirus firewall is blocking Chrome, add an exception for it in your security software settings to allow web access.

5. Reset Chrome Settings

Custom tweaks can cause conflicts. Click three dots > Settings.

Go to Advanced.

Select Reset settings > Restore settings to their original defaults > Reset settings.

Refresh and test. This has resolved the issue for me in stubborn cases.

These steps should get you back online. If not, run a malware scan or update network drivers.
