The best way to remove 1.1 400 errorsAugust 22, 2020 by Louie Sharp
This guide will help you if you see error 1.1400. On this page. The HyperText Transfer Protocol 400 Invalid Protocol (HTTP) response status code indicates that the server cannot or does not want to process the request due to an error that is perceived as a client error (for example, invalid request syntax, invalid request message frame, or misleading request ).
Bad Request Error 400 occurs when the request sent to the website server is invalid or corrupted and the server receiving the request cannot understand it. Sometimes the problem is with the site itself and there is nothing you can do about it. However, in most cases the problem can be fixed: you may have entered your browser address or cached incorrectly, which is causing the problem. Here are some solutions you can try.
What Is Bad Query Error 400?
Bad Request Error 400 occurs when the server cannot understand the requested request. This is called a 400 error because it is the HTTP status code that the web server uses to describe this type of error.
Bad Request Error 400 may occur because the request contains a simple error. Perhaps you entered an invalid URL and the server cannot return a 404 error for some reason. Or your web browser is trying to use an expired or invalid cookie. Some servers that are not configured correctly can also throw 400 errors instead of the more useful errors in certain csituations. For example, if you try to upload an oversized file to some websites, you may see a 400 error instead of an error indicating the maximum file size.
Similar to 404 and 502 errors, web designers can customize the display of 400 error. Different websites can display 400 pages that look different. Sites may also use slightly different names for this error. For example, you can see things like:
Often you can do something to fix the 400 error, but be specific about what can be difficult due to the vague nature of the error. Here are some things you can try.
Refresh The Page
Refreshing the page is always worth a try. Error 400 is often temporary and a simple update can help. Most browsers use the F5 key to refresh, and they also offer a refresh button somewhere in the address bar. The problem is not solved very often, but it only takes a second to try.
Check The Address
The most common reason for error 400 is incorrectBut entered URL. If you entered the URL in your address field yourself, you may have entered a mistake. If you clicked on a link on another website and got a 404 error, it is also possible that the link on the Links page was entered incorrectly. Check the address and see if you noticed any obvious mistakes. Also look for special characters in the URL, especially those that are not common in the URL.
If the URL you want to go to is descriptive (or if you know roughly the name of the expected post or page), you can search the website using the keywords of the address. In the following example, you cannot tell by the URL itself if something is misspelled, but you can see some words in the title of the article.
This same solution also works if the website you are trying to navigate to has changed the URL for some reason and has not redirected the old address to the new one.
And if your website doesn't have its own search box, you can always use Google (or your favorite search engine). Just useUse the "site:" operator to search only for keywords within a site.
In the image below, we are using Google and the search term "Site: Howtogeek.com focal" to search for keywords only on Howtogeek.com.
Clear Your Browser Cookies And Cache
Many websites (including Google and YouTube) report error 400 because the cookies they read are corrupted or out of date. Some browser extensions may also change your cookies and cause 400 errors. It is also possible that your browser has cached a corrupted version of the page you are trying to open.
To test this feature, you must delete your browser cache and cookies. Clearing the cache doesn't have much of an impact on your browsing experience. However, some websites may take a few seconds to load as all previously cached data is loaded again. Deleting cookies means that you should be logged into most websites.
To clear your browser cache, you can follow this step by step guide where you will learn how to clear the cache in all popular desktop and mobile browsers.
Clear Your DNS
Your computer may have stale DNS records that cause errors. Simple deletion of DNS records can help solve the problem. It is easy and easy to test. We have detailed instructions on how to reset DNS cache on Windows and MacOS.
Check File Size
If you upload a file to a website and get a 400 error, the file is likely to be too large. Try uploading a smaller file to confirm if this is causing the problem.
Try Other Sites
If you tried to open one website and get 400 errors, try opening other websites to see if the problem persists. In this case, there might be problems with your computer or network equipment, and not with the website you are trying to open.
Restart Your Computer And Other Devices
This solution is not difficult at all, but restarting the computer and especially network devices (routers, modems) is a common way to fix manyserver errors.
Contact The Site
If you've tried all the solutions and the error persists, there might be a problem with the website. Try to contact the site through the contact page (if it works) or through social media. Perhaps they already know about the problem and are working on a solution.
