Some extensions can disrupt your network connection and trigger an access-denied error.

Steps:

  1. Open Google Chrome.
  2. Click on the three-dot menu in the top-right corner.
  3. Go to More tools > Extensions.
  4. Toggle off each extension one by one by disabling the slider.

Pro Tip: Start by disabling extensions that are related to ad-blocking or VPNs since they often interfere with connections.

3. Disable Proxy Server

Misconfigured proxy server settings are a common source of network problems.

Steps:

  1. Right-click on the Windows Start button.
  2. Select Network Connections.
  3. On the left side, click on Proxy.
  4. Under Manual proxy setup, click Edit.

Your computer’s network settings might be misconfigured. Resetting internet settings can restore normal operation.

Steps:

  1. Press Windows + R keys to open the Run dialog box.
  2. Type inetcpl.cpl and click OK.

Anti-virus programs, firewalls, or VPNs often block internet access if they perceive a network as a security risk.

Steps:

  1. Temporarily disable any installed anti-virus programs.
  2. Similarly, deactivate your Windows Firewall and VPN applications like NordVPN
  3. Check if you can now connect online.

Pro Tip: If using a VPN like NordVPN, ensure it’s setup correctly and on the latest version. Sometimes a simple upgrade or server switch can resolve access issues.

8. Restart Router and Modem

Network glitches are sometimes caused by your router or modem. A simple reboot could be the answer.

Steps:

  1. Turn off both your router and modem.
  2. Wait for at least 30 seconds.
  3. Power them back on and wait until all the connection lights are steady.
  4. Try reconnecting to your browser.

Note: Restarting your router often resolves temporary glitches. If recurring issues persist, consider network backup solutions like MiniTool ShadowMaker to safeguard your configurations before deeper troubleshooting.

Malicious software can make unauthorized changes to your internet settings, leading to errors like “ERR_NETWORK_ACCESS_DENIED.”

Steps:

  1. Use a dedicated malware removal tool to scan your device for infections.
