Many people have problems when they try to use search engines. One of these problems is called Error 400 Bad Request. This error means that the search engine cannot process the request to find the desired website. As a result, the user cannot access the URL because the server (e.g., Google) cannot understand or process the request. Several issues can cause this error, such as the request being sent to the wrong place, improperly formatted, blocked URL or web server, or the request being made incorrectly.
If you are looking for information about error 400 and how to fix it on the internet (Google, Bing, Safari), don’t worry. This article will address all your questions. However, if the error is on the website server, only the website owner can fix it.
This article will explain the causes of error 400, its impacts and effects, and how to quickly and easily resolve it.
There are several types of 400 error messages that you might see when you try to access the internet. These all indicate that the server can’t process a request. So, it’s a good idea to know the different types of these error messages so you don’t get confused when you encounter problems with different URLs. Here are some examples of 400 error messages:
Not everyone uses the same server. The 400 error message can also look different in different browsers. To help you understand this error message, we’ll show you some example images for common browsers.

When Google as a browser is unable to process a request, a message like 400. That’s an error. Your client has issued a malformed or illegal request will appear.

If you use Google Chrome on your phone and laptop, then error 400 bad request will display the message This page isn’t working and If the problem continues, contact the site owner HTTP ERROR 400. This means Chrome cannot process the URL. The cause could be the cache on your device or on the website server itself.

This is how an error message in Microsoft Edge looks. It is similar to the error 400 message on Google Chrome.


Other browsers show a 400 error message, but Mozilla displays a blank page. The issue is the same as with other browsers, where the server can’t process a URL. If you use Mozilla, you may have seen this before.

To understand the cause, we will first discuss how the website system works. Generally, a website has a lot of content, such as an article about SEO Optimization for Google Search Generative Experience. Then someone finds the article on Google and visits it, the browser automatically sends a request to the Gugelin.com server to be processed. After that, the article can be read. That’s how the website server works.
If the article above shows a 400 error, it means the URL is likely broken or changed. This problem can only be fixed by the website owner. However, it is different if the 400 bad request error occurs due to user error. Here are some examples that you might experience without realizing it:
If Error 400 Bad Request continues to occur, it can be very serious. Additionally, most users perform the majority of their activities on the internet. These individuals have the most to lose if they are affected by Error 400 Bad Request.
Remember that sometimes you might need to delete some stored data in your browser to fix Error 400 Bad Request. Whether the data is important or not, browsers that don’t store connection data are usually much faster.
However, you may find browsing the web a bit of a hassle if you don’t have the stored data. The data is like a copy stored in Edge Caching. Here are some of the benefits:
Nevertheless, there are times when clear benefits for users unexpectedly result in errors, such as Error 400 Bad Request. This condition may require you to delete the stored data. The solution is as follows.
A 400 Bad Request that appears when accessing a URL usually occurs because the URL is incorrect, has the wrong syntax, or contains invalid characters. A website link is like a home address; if the address is wrong, it will never reach its destination.
Therefore, first make sure that the URL or domain address is correct or not. Each URL usually consists of a domain name, file name, hyphen (-), or percent character (%). For example, www.gugelin.com/website is the correct address, but if you change the / to %, or gugelin.com to gugalin.com, error 400 will occur. So, to overcome this, first make sure that the URL and domain name are correct or not.
The second method is to delete the corrupted data or files (cache) stored locally on the browser you are using. The types of cache files that are usually stored are as follows:
All types of files are already stored in the browser you usually use. To fix this, the cache in the browser needs to be cleared.
If you are using Google Chrome, click the three dots icon in the top right corner, then select Clear browsing data.

After that, a popup window will appear and you can check the cached images and files option, then click the delete data button. All image and file data will be deleted from the browser. Oh, you need to set the Time range above to all time to ensure that all data is completely cleared.

Oh, by the way, please note that we are using Google Chrome. For other browsers, the steps may vary but not by much. Essentially, look for the delete and cache instructions.
If clearing the cache still results in a 400 error, try clearing your browser’s cookies as well. Sometimes just a few corrupted cookies can cause the error page to appear. So, it’s best to delete all of them for safety.
The method is the same as clearing the browser cache. For more details, see the image below:

If you’re using the Bing browser, try following the steps shown in the image below:





If you have cleared your cache and cookies, try reloading the website that displayed the Error 400 Bad Request. Because clearing the cache and cookies resets the browser, the website might take a long time to load or might not load properly when you visit it again.
Finally, if the problem was caused by cache and cookies, then it will be resolved immediately. If that doesn’t work, try the following method.
The above method doesn’t work very well. Instead, try searching for the keyword in a search engine. Look at the URL that previously had a 400 error, and then examine the title. For example: https://gugelin.com/optimasi-seo-untuk-google-search-generative-experience/. The URL has a title, so enter that title into the search feature if the website has one.
If there is no search feature, you can use another method: search on search engines such as Google or Bing. Follow the instructions below:

If you still have problems, try turning off your browser extensions. We have found some notes indicating that extensions sometimes block requests to web servers. This can cause the server to think the request is invalid and display a 400 error message.
There have also been cases where cookies become corrupted due to an extension installed in the browser. As we have explained, one or two broken cookie URLs can cause a 400 Bad Request error. You can see how to turn off the extensions in the image below.


When you get to the list of installed extensions, you can disable or remove them by clicking REMOVE. After that, try reloading the error page to see if you can access it. If you can, it means that the extension is the main problem.
If you don’t want to remove all the extensions, try turning them off one by one while refreshing the web page until you find the problem.
If the URL page that’s giving you an error is a website that specializes in uploading files, you’ll need to check whether the file is too large. Usually, websites have a size limit.
The solution is to resize the file to a smaller size, for example, by using a compressor application. Then try uploading it again. Remember that reducing the size of a file will also reduce the quality.
If you still can’t resolve the error 400 problem after trying all of the above methods, try contacting the website owner and reporting the inaccessible URL. This is because the cause of the error could be an issue with the website’s settings.
To contact the website owner, find the Contact Us menu and send a report about the problem you are experiencing. If you have the website’s email address or social media account, you can send a report through that medium. Wait for a response until the website owner fixes the Error 400 Bad Request error.
After reading this article, you will understand what Error 400 Bad Request is, what causes it, how it affects you, and how to solve it. Firstly, the error can occur on your device and can be fixed by clearing the cache and cookies on your browser. There are also several other ways to solve the problem.
If that doesn’t work, the problem may be with the website’s setup. If this is the case, you should contact the website owner and report the URL Error 400 problem through the provided contact information.
