The ERR_NETWORK_ACCESS_DENIED error is a common message you may see when using a browser. This error occurs when your firewall blocks a connection to a website. It can also happen if there is an issue with your internet connection.

More specifically, it means the connection between your computer and the web server you’re trying to access was lost before any data could be transmitted.  In this article, we will discuss what causes ERR_NETWORK_ACCESS_DENIED, why you might get it, and how you can fix it. 

Why am I getting the ERR_NETWORK_ACCESS_DENIED error?

If you are getting an ERR_NETWORK_ACCESS_DENIED error on your computer, there could be several reasons behind it. These include:

  • Firewall/antivirus restrictions –  If you have antivirus software installed, there may be a chance that it has blocked access to whatever website or file you’re trying to open.
  • Proxy server – You may be using a proxy server that requires authentication or authorization to send data through it.
  • Virus infection – Your computer may be infected with malware or adware that prevents the website’s content from properly loading onto the browser window.
  • Server overload – When your Internet provider’s servers are overloaded with requests from other users, it can take longer to process your request. This way, you get an access denied message.
  • Connection issues – If your computer has a bad or unreliable internet connection, you may have trouble connecting to sites.
  • Incorrect URL/credentials – You may have entered an incorrect URL in your browser or entered an invalid username or password when prompted for authentication information.
  • Cookies and cache – Your browser may be set to not accept cookies from the website you are visiting or has them disabled for this website.

How do I fix the ERR_NETWORK_ACCESS_DENIED error?

Before you do anything else, try these basic workarounds:

  • Check that the Ethernet cable is plugged in securely on both ends, and check to make sure the other end of the cable isn’t broken or damaged. 
  • Ensure you have a good internet connection and optimal network speeds.
  • Verify that your network drivers are up-to-date.
  • Clear your browser’s cache and cookies.
  • Disable any extensions that may be causing the issue.
  • Try opening the website using an incognito window or private browsing mode. Check out the differences between Chrome’s incognito mode and Firefox’s private mode.
  • Reboot your router by unplugging it from its power source for 30 seconds and then plugging it back in.
  • Switch to a different browser, such as Opera, and see if the error persists.
