401 Unauthorized: Causes and Troubleshooting

This error message will certainly appear normally after a user tries to access a website that they are not allowed to access to a website, or after a failed login attempt. As a website owner, you can add password defense to your website using your cPanel account. This can be a wonderful extra layer of security that restricts access to your administrator location, e.g. For example, the wp-admin folder on a Word Press site.

401 Not authorized: causes and troubleshooting 1

Why is I seeing an unauthorized 401 error?

Browser cache and cookies

You may encounter 401 errors due to old and outdated cookies and the cache in your browser. If you forget to clean up the old cache, it can lead to 401 unauthorized errors. Due to old cookies and cache, the server receives the wrong login information from the browser. And in a result, you will be faced with this error.

Plugin incompatibility

If you install a firewall or other security plug-ins and later wind up changing the username password or migrating the site, this security plug-in may view it as malicious activity. Then this plugin will block your access and you will get 401 unauthorized errors.

Wrong url

Sometimes we find ourselves copying, pasting, or typing the wrong URL into the browser. Sometimes webmasters change the url without proper redirection. These things can cause you to get a 401 error.

Step-by-step guide on how to fix the 401 HTTP error.

Check again the url you want to visit. The first thing we can do to fix this error is to make sure that the correct url is being visited. An incorrect url leading to the dead end can show 401. This is the first step you need to take to resolve the 401 error.

Try to uninstall the plugin

The firewall and security plug-in may be blocking access to the site. You can remove these plugins from your site to fix the 401 error. Make sure to deactivate the plugin one by one so that you get exactly the faulty plugin. Try to reconfigure it. If it still behaves badly, remove it.

Clear your browser cache.

Cleaning up the browser is equally important in clearing our stressful minds. Please make sure that you delete all caches and cookies regularly. So the browser will keep all valid credentials and never get a 401 HTTP error.

Flush DNS

You can try flushing your DNS. To do this, enter ipconfig / flushdns in the command prompt and click ENTER.

Reset the WordPress password.

When someone tries to log into your website, WordPress may be blocking access to a wp-admin page. You can visit after a few minutes or reset your password. If you do not get the reset option on the front end, you can do this via your Cpanel.

Reinstall wordPress and restore the backup.

We always recommend our visitors to back up the website regularly. Securing your website can save you from many disasters. If all options have failed, you can reinstall your WordPress file and reinstall your website backup. If you don't use WordPress, please contact your hosting provider.
