How to Fix ERR_NETWORK_ACCESS_DENIED (Google Chrome)
Quick Answer
The ERR_NETWORK_ACCESS_DENIED error in Google Chrome indicates that the browser is blocked from accessing the network, often due to security software or system settings. The fastest fix often involves checking your firewall or antivirus settings to ensure Chrome is not being blocked.
What Causes This Error
- Firewall or antivirus software blocking Google Chrome's network access.
- Incorrect network proxy settings.
- Corrupted Chrome browser profile or extensions.
- Outdated or misconfigured network drivers.
- Windows Defender Firewall or other system security features preventing access.
Step-by-Step Fixes
1Check Firewall and Antivirus Software
- Open your computer's firewall settings. For Windows, search for 'Windows Defender Firewall' in the Start menu. For macOS, go to 'System Settings' > 'Network' > 'Firewall'.
- Locate the section that manages allowed apps or programs. Ensure Google Chrome is listed and has full outbound and inbound network access.
- If using third-party antivirus or internet security software, open its interface and look for network protection, firewall, or application control settings. Verify that Chrome is not blocked.
- Temporarily disable your antivirus or firewall software (if safe to do so and only for a brief test) and try accessing the website again. If the error resolves, re-enable the software and add an exception for Chrome.
- Consult your security software's documentation for specific instructions on how to add exceptions or manage application network access.
2Reset Google Chrome Network Settings
- Open Google Chrome.
- Type 'chrome://settings/system' into the address bar and press Enter.
- Scroll down to the 'Proxy' section. Click on 'Open your computer's proxy settings'. This will open your operating system's network proxy configuration.
- For Windows: In the 'Proxy' settings window, ensure 'Automatically detect settings' is enabled and 'Use a proxy server' is turned off, unless you specifically require one for your network.
- For macOS: In 'Network' preferences, select your active network connection (e.g., Wi-Fi), click 'Advanced', then go to the 'Proxies' tab. Ensure no unwanted proxy configurations are active. Deselect any proxy protocols you are not using.
- Close the proxy settings and restart Google Chrome to apply changes.
3Clear Chrome Browser Data and Cache
- Open Google Chrome.
- Click the three-dot menu icon in the top-right corner of the browser window.
- Navigate to 'More tools' > 'Clear browsing data'.
- In the 'Clear browsing data' window, set the 'Time range' to 'All time'.
- Ensure 'Browsing history', 'Cookies and other site data', and 'Cached images and files' are checked.
- Click the 'Clear data' button. Restart Chrome after the process completes.
4Disable Chrome Extensions to Fix ERR_NETWORK_ACCESS_DENIED
- Open Google Chrome.
- Type 'chrome://extensions' into the address bar and press Enter.
- Review the list of installed extensions. Toggle off each extension one by one by clicking its blue switch.
- After disabling an extension, attempt to access the problematic website. If the error resolves, the last disabled extension was the cause.
- Once the problematic extension is identified, either keep it disabled or remove it by clicking the 'Remove' button.
5Update or Reinstall Network Drivers
- For Windows: Right-click the Start button and select 'Device Manager'.
- Expand 'Network adapters'. Right-click on your network adapter (e.g., Ethernet or Wi-Fi adapter) and select 'Update driver'.
- Choose 'Search automatically for updated driver software'. If no new drivers are found, visit your computer manufacturer's website or the network adapter manufacturer's website to download the latest drivers manually.
- After updating, restart your computer.
- If updating does not resolve the issue, you can try uninstalling the driver (right-click the adapter, select 'Uninstall device') and then restarting your computer. Windows will typically reinstall a generic driver automatically.
