3]Try private browsing

If you have changed a lot of settings, installed extensions, or used a proxy or VPN recently, it is recommended that you visit the same website in incognito mode. Incognito mode does not preserve these settings which is why it works like safe mode. If it works fine, you should undo all changes and try normal browsing mode again.

4]Disable extensions

Sometimes installing countless extensions can cause the same problem to occur on your PC. When you install different proxy and VPN extensions in the browser, it may cause conflict and as a result you will not be able to open any website. Therefore, it is recommended to disable all installed extensions and see if that fixes the problem. If so, you can enable one extension at a time to find the culprit.

6]Scan the PC with the Adware Removal Tool

If your computer contains adware, it may prevent you from opening different websites. Adware can work strangely on your computer, and this is one of them. Therefore, you can scan your computer with various anti-adware tools. FYI, you have a few options including AdwCleaner, Ultra Adware Killer, etc. However, if you are already using another tool, you can definitely use it as well.

Note: All of these solutions mentioned above are for regular users. However, if you are in charge of a website, you can also try the following troubleshooting tips and tricks. Most of these solutions are based on WordPress. However, you can try it though using any other CMS.

7]Delete cookies via Cache plugin

As mentioned in the first solution, this HTTP error is caused by incorrect cookie settings. So, if the Cache plugin is not set correctly or is not compatible with the server, you may encounter this problem as well. So you have these things in your hands:

  • Clear the cache via the cache plugin. Whichever plugin you use, it has an option to delete the cache.
  • Disable the Cache plugin and check if you can open your website or not.
  • Set the Cache plugin correctly. You can get help from your server provider’s support.

8]Check htaccess

If you are using Apache, HTACCESS plays a vital role in configuring many things. So, check your .htaccess file for any unnecessary code. You can also choose the default .htaccess file. FYI, this is the default .htaccess file:

# BEGIN WordPress

RewriteEngine On

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

RewriteBase /

RewriteRule ^index\.php$ - [L]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . /index.php [L]

# END WordPress

You can find this hidden file in the root directory.

Note: Do not delete this file or make any changes unless or until you have the appropriate knowledge.

9]Check the header icon

If you recently installed a new icon in the header file and the problem started after that, you should remove it immediately. In most cases, you may need to enter different lines of code to verify that your website is using one service or another. In such cases, you can remove these codes and see if that fixes the problem. For your information, you can consult header.php your theme file.

10]Set Website Permalink

If you have recently moved from one server to another, you may need to define and save the permalink structure. Even if you haven’t changed the structure at all, you can just click on File Save Changes button to solve this problem. If you use WordPress, you can log into the WordPress dashboard with an administrator account and access Settings > Permalinks.

Next, make sure you are using the correct permalink structure and click Save Changes button. Once done, you can open the site normally.

11]Disable URL Redirect Extensions

If you are in the affiliate marketing business, anonymizing or hiding URLs is a common practice. These plugins hide the original URL and change it into something fancy and trustworthy. On the other hand, if you use a URL redirect plugin to redirect old URLs or 404 error URLs, it can also create the same problem. That is why it is highly recommended to disable these plugins and check if you can open the website normally or not.

What is HTTP Error 431?

HTTP 431 error mainly occurs in two different cases. First of all, if the website you want is having problems with cookies, it is possible that this error can occur. On the other hand, if the requested URL is too long, Chrome may not be able to process the permalink. In such cases, you can disable referral code, header.php, URL redirect plugins, etc.

HTTP error 431 means that the HTTP headers are too long for the servers to handle and says “Request response status is too large for header fields”. To fix this problem, you can refer to the solutions we mentioned above.

Before knowing the solutions, let’s take a look at why the error code appears on the screen. There are several reasons why HTTP 431 error is displayed. We have mentioned some of them below:

  • Website or browser cache tends to get corrupted and is the only cause of the error code. You can delete cookies from the site. And if that doesn’t work, you can delete your site data or Chrome history. They both work.
  • If the account is corrupt, you will likely see the error message. Therefore, it is necessary to create a new user account and see if the problem is still there.
  • Chrome installation often gets corrupted and later causes problems for users while using websites, you can reinstall Chrome to get rid of this error code.

What does a very large order title mean?

You may see a request header or a cookie that is too large when the server thinks the cookie size for this domain is too large or corrupt. As a result, it will refuse to serve you the web page. This will force your browser to display 400 invalid requests, request header or cookie is too large or a fatal error.
