How to Fix ERR_NETWORK_ACCESS_DENIED Error on Windows 11: Step-by-Step Solutions

Encountering the ERR_NETWORK_ACCESS_DENIED error on Windows 11 can be frustrating, especially when you just want to browse the internet smoothly. This error usually means your network connection is being blocked or restricted in some way.

There are several simple steps you can take to fix this issue, starting from the easiest checks to more detailed troubleshooting. Each step explained here is designed to be clear and easy to follow, even if you’re not very tech-savvy.

By carefully following these instructions, you can restore internet access and prevent this error from appearing again. Let’s get started with some quick notes before diving into the solutions.

Understanding why this error happens will also help you avoid similar problems in the future.

Quick Note: Prerequisites and Basic Checks

Before you begin troubleshooting, make sure of the following:

  • Your internet connection is active and stable. Try opening a different website or app to confirm.
  • You have administrator access on your Windows 11 computer to make system changes.
  • Any VPN or proxy services you use are temporarily disabled, as these can sometimes cause network issues.
  • Your Windows 11 system is updated. Some network errors happen due to outdated system files.

Step 1: Restart Your Computer and Network Devices

This is the simplest fix and often resolves temporary glitches. Restarting your PC refreshes system processes, and rebooting your router or modem resets your internet connection.

  1. Click the Start menu, then select Power and choose Restart.
  2. Turn off your modem and router by unplugging them from the power source.
  3. Wait for about 30 seconds, then plug them back in and wait for the devices to fully power up.
  4. After your PC restarts, try accessing the website or service again.

This step helps clear any temporary network conflicts or software hiccups causing the error.

Step 2: Disable Firewall or Antivirus Temporarily

Your firewall or antivirus might mistakenly block network access, leading to the ERR_NETWORK_ACCESS_DENIED error. Temporarily disabling these security features can help identify if they are the cause.

How to Disable Windows Defender Firewall

  1. Press Windows + S and type Windows Security, then open it.
  2. Click on Firewall & network protection.
  3. Select the active network profile (it will say Active).
  4. Toggle off Microsoft Defender Firewall.

How to Temporarily Disable Third-Party Antivirus

Right-click the antivirus icon in the system tray (bottom-right corner) and look for an option like Disable or Pause protection. If unsure, consult your antivirus provider’s support guide.

Important: Remember to re-enable your firewall and antivirus after testing to keep your system protected.

Step 3: Check and Reset Network Settings

Sometimes, incorrect network settings cause access denial. Resetting these settings restores default network configurations which often fixes related errors.

How to Reset Network Settings on Windows 11

  1. Open Settings by pressing Windows + I.
  2. Go to Network & Internet.
  3. Scroll down and click Advanced network settings.
  4. Under More settings, click Network reset.
  5. Click the Reset now button and confirm.
  6. Your PC will restart automatically.

This process will remove and reinstall all network adapters and set all networking components back to their original settings.

Step 4: Run Windows Network Troubleshooter

Windows 11 has a built-in troubleshooter that can detect and fix common network problems automatically.

  1. Open Settings (Windows + I).
  2. Navigate to System > Troubleshoot > Other troubleshooters.
  3. Find Internet Connections and click Run.
  4. Follow the on-screen instructions to let Windows diagnose and fix issues.

This tool is helpful because it can identify specific network errors without requiring advanced knowledge.

Step 5: Check Proxy Settings

If your PC is set to use a proxy server incorrectly, it could block network access and cause this error.

To Disable Proxy Settings:

  1. Open Settings (Windows + I).
  2. Go to Network & Internet > Proxy.
  3. Turn off Use a proxy server under the Manual proxy setup section.
  4. Also, make sure Automatically detect settings is turned on.

Disabling incorrect proxy settings ensures your PC connects directly to the internet.

Step 6: Flush DNS and Reset TCP/IP

Corrupted DNS cache or TCP/IP stack can cause network errors. Flushing and resetting them often solves connectivity problems.

How to Flush DNS and Reset TCP/IP:

  1. Press Windows + S, type Command Prompt, right-click it, and select Run as administrator.
  2. In the command window, type the following commands one by one, pressing Enter after each:
ipconfig /flushdns
netsh int ip reset
netsh winsock reset
ipconfig /release
ipconfig /renew

Restart your computer after running these commands. This fixes many network-related issues by clearing old settings and refreshing network connections.

Step 7: Update Network Drivers

Outdated or corrupted network drivers can cause access denied errors. Updating them ensures your hardware communicates properly with Windows 11.

  1. Press Windows + X and select Device Manager.
  2. Expand the Network adapters section.
  3. Right-click your active network adapter (Wi-Fi or Ethernet) and select Update driver.
  4. Choose Search automatically for drivers and follow prompts if updates are found.

If no update is found, you can also visit your PC or network adapter manufacturer’s website to download the latest drivers manually.
