Ensure the URL is correct<\/h3>\n\n\n\n<p>One of the most common mistakes that any users generally make is typing an incorrect URL in the browser&#8217;s address bar. Therefore, you need to recheck the entered URL carefully and make sure there is no misspelled or any missing character is present.<\/p>\n\n\n\n<p class=\"justify\">If you have entered a wrong, outdated, or misspelled URL, you might encounter an Error code 401 message. But you do not need to panic. This error message simply indicates that the URL you were trying to access doesn&#8217;t exist and it shows up as a &#8220;401 unauthorized access&#8221; response from the server.<\/p>\n\n\n\n<p class=\"justify\">For your better understanding, let us take an example. Suppose, you have bookmarked a page or saved its address in your browser. But over time, things might change. The page you were trying to visit might be updated or even deleted.<\/p>\n\n\n\n<p class=\"justify\">To investigate further, you can try visiting the website&#8217;s homepage and searching for the link to the page that is causing the &#8220;Unauthorized 401&#8221; error. If the page opens without any issue, you need to compare the match the URL of the page to the one that initially gave you the error.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Ensure-correct-Authentication-credentials\">2. Ensure correct Authentication credentials<\/h3>\n\n\n\n<p>Sometimes, you might even encounter the 401 Error code when you are trying to access a locked resource or content that is password protected. This means you have provided invalid authentication credentials, due to which you&#8217;re denied access to the resources.<\/p>\n\n\n\n<p class=\"justify\">Here is what you can do to avoid such issues. First, take your time and double-check the login credentials such as user ID and password before proceeding further.<\/p>\n\n\n\n<p class=\"justify\">If you are confident that you&#8217;ve entered the correct credentials, then it is better to change your password. This will help you to reset your password and have the right credentials to access the resources.<\/p>\n\n\n\n<p class=\"justify\">However, in case you are unable to access your password-protected website, Check out our complete guide on &#8220;<a href=\"https:\/\/www.wpoven.com\/blog\/reset-wordpress\/\" data-type=\"URL\" data-id=\"https:\/\/www.wpoven.com\/blog\/reset-wordpress\/\" target=\"_blank\" rel=\"noreferrer noopener\">How To Reset WordPress &amp; Start Over Easily?<\/a>&#8220;.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Clear-your-browser-cache-and-cookies\">3.

These are specially built and designed to block any suspicious activity found and return a 401 error message. <\/p>\n\n\n\n<p class=\"justify\">Another possibility can be, incompatibility issues. Some WordPress plugins can conflict with your website and trigger such errors. If this is the cause, the best thing you can do is to disable all the installed WordPress plugins and check if this fixes the issue.<\/p>\n\n\n\n<p><strong>Step 1<\/strong>: Log in to your WordPress admin dashboard<\/p>\n\n\n\n<p><strong>Step 2<\/strong>: Navigate to the &#8220;Plugins&#8221; menu option on the left-hand side of the dashboard.<\/p>\n\n\n\n<p class=\"justify\"><strong>Step 3<\/strong>: A list of installed plugins will be displayed.
