Steps To Fix HTTP 400 Bad Request In Windows 10 Computer?

Fix 1: Try Changing The Browsers

If you are in a hurry and want to surf the internet but are facing the HTTP 400 Bad Request error, then the best possible solution is to use a different browser. The All-New Microsoft Edge, which is based on Chromium, is the only browser that can be compared with Google Chrome. You can use either one instead and check if the same issue reoccurs. You can choose any browser your like.

Cookies are bits and pieces of information stored in our computer by various websites. This helps to load websites faster as not all the content is downloaded again. The cookies stored are always being modified depending on the latest version of the site, and this process can cause duplicate and corrupted cookies. This results in HTTP 400 Bad Request error which prevents you from surfing the internet.

The solution, of course, would be to remove the cookies and other temporary files stored that would not only get rid of the HTTP 400 Bad Request error but also help retrieve storage space consumed by these potentially unwanted files. There are two ways to clean them: Manual & Automatic method.

Manual Method: This includes manually cleaning cookies and cache for every browser by navigating to the settings and performing the cleaning task.

Automatic Method: This method involves using an application to optimize the computer.

How to Clear Cookies from Browsers using a Software?

It is quite convenient to use optimizing software and clear all the cookies and cache files in one go. This will help clean and maintain the system and fix any errors along with HTTP 400 Bad Request error.

Fix 3: Check The URL.

One of the common reasons on a large scale for the HTTP 400 bad request error is due to the incorrect URL. The URL includes spellings, spaces, paths etc. which must be checked and confirmed. Only a correct address will lead to the proper webpage.

Fix 4: Log Out And Log In Again

There are a few websites that support user authentication. This means the user must sign in every time he/she visits the site. If you remain signed in for an extended time, then time can sometimes generate HTTP 400 bad request error due to strings from other past sessions. The solution would then be to remove the cookies containing the login information by logging out once and signing back in.

Fix 5: Recent Installations

Check your system for any recent app installations including extensions on your browsers. Due to lack of compatibility, the 400 HTTP bad request issues often occur and can be fixed by removing the extension, add-on or application causing this. There is no precise method to ascertain the app but can be identified by removing each newly installed app, one by one. This is also known as the trial and error method.

Fix 6: Reset The Browser

The final option to resolve this error is to reset the browser, which means you will lose all the saved passwords and settings. However, your bookmarks will stay intact.

To reset Chrome, follow these steps:

Step 1: Launch Chrome and click on the three dots on the top right corner.

Step 2: Click on Settings and scroll down and click on Advanced.
