Stuck on a 401 Error Code? Common Causes and Fixes
Are you building your own website and encountering a 401 error code? In this article, we’ll cover some common causes and help you solve them.

Are you building your website and stuck with a 401 error code? Don’t worry—this is a common issue, especially for beginners. A HTTP error 401 means your website is blocking access. It's like a locked door that needs the right key.
This 401 HTTP code usually shows up when your login details are wrong or missing. You may have entered the incorrect username or password. Sometimes, your browser saves old login information, which can also cause the HTTP error code 401. In some cases, the problem comes from website settings, plugins, or security tools. In this article, we’ll explain the common causes of the 401 error and show you how to fix them step by step. You can follow along even if you don’t know much about coding. Let’s fix that HTTP 401 error code and get your website running again!

#01 What is a 401 Error Code?
A 401 error code is a message you see when a website blocks your access. You might also see it called 401 HTTP, HTTP error 401, or HTTP error code 401. This happens because the site thinks you are not allowed to enter. For example, you might type the wrong username or password, or your web browser may have saved old login details. When you see a 401 error, it feels like a locked door you can’t open. That is very frustrating, especially if you are new to making websites and do not know why it happened.
Fixing a 401 error quickly is essential because visitors leave and go to other sites every minute your page is locked. A slow or broken site also looks unprofessional. For people using your site, a fast fix means they can see your content or buy your products without trouble.
✅ Quick Tip Box: A 401 means “unauthorized” — the website won’t let you in!
Learning what causes HTTP error 401 and how to solve it will help you keep your site running smoothly. In the following sections, we will show you the most common reasons for a 401 HTTP code and guide you through easy steps to fix it.
#02 Common Causes of 401 Error Code
Here are some common causes of a 401 error code. If you are seeing a 401 HTTP code, it means the website thinks you are not allowed to see the page. Let’s look at some simple reasons why this might happen — and how to fix them!

1. Incorrect Login Details
This is the most common reason for a 401 error. You might type the wrong username or password by mistake. Your login may have expired, and you need to log in again. Always double-check your username and password.
2. Missing or Invalid Token
If you use tools like APIs or admin panels, you might need a special “key” or token to get in. If this token is missing or expired, you’ll see an HTTP 401 error code. Try logging out and back in again or refreshing your token.
3. Plug or Theme Problems (for WordPress users)
If you use WordPress, an old plugin or theme might mistakenly block users. Some security plugins may have rules that cause the 401 error. Try updating your plugins and themes. You can also turn them off one by one to find the problem.
4. Server Settings Error
Sometimes, the problem is not you—it’s the server. A broken or poorly written .htaccess file can cause an HTTP error code 401. If you don’t know how to check this, ask your hosting provider for help.
5. Browser or Cache Problems
Your web browser stores cookies and login info. If this info is old or wrong, you could see a 401 HTTP code. Try clearing your browser cookies and cache, or use a different browser to see if the problem goes away.
Understanding these simple causes of the HTTP error code 401 will help you fix the problem quickly and keep your website working well!
#03 How to Fix a 401 Error: Step-by-Step Guide
If you see a 401 error code, don’t worry! It just means the website won’t let you in. This happens when the site thinks you're not allowed to view the page due to authentication issues. Sometimes, it's caused by incorrect login details, expired credentials, or server misconfigurations. But fixing a 401 HTTP error is easier than you think. Just follow these simple steps, and you can resolve the issue quickly without needing technical expertise. Whether it's clearing your cache or checking your login credentials, you can get back on track in no time!
Step1: Double-Check Your Login Info
The most common reason for an HTTP error 401 is wrong login details. Check your username and password. Make sure there are no typos. If you're not sure, try resetting your password.

Step2: Clear Browser Cache and Cookies
Old login info can get stuck in your browser, causing a 401 HTTP code. Go to your browser settings and clear the cache and cookies. Then, try opening the site again. You should log in one more time.

Step3: Turn Off Security Plugins (for WordPress Users)
Sometimes, a plugin meant to protect your site may block you by mistake. This can cause a 401 error code. If you use WordPress, try turning off security plugins one at a time to find the problem. Don’t forget to turn them back on when done.

Step4: Check the .htaccess or the Authentication File
Your site may have a file called .htaccess or another security file. If it’s broken or has the wrong rules, it can cause an HTTP error code 401. You can open this file in your hosting panel. If you’re not sure what to change, ask an expert or your web host.

Step5: Ask Your Hosting Provider for Help
If you’ve tried everything and still see an HTTP 401 error code, your hosting company can help. They can check the server and fix the issue for you.
💡 Pro Tip: Always back up your website before making any changes to server files!
Fixing an error 401 helps your site run better and keeps visitors happy.
