What Does 400 Bad Request Error Mean And How Fix It?

Given the amount of time we spend online these days, it is little wonder that we are exposed to so many errors. To the lay person, the appearance of an error when browsing the web can be worrying. However, many errors can be quickly sorted out with a few simple steps. In some cases, the error may not even be at your end. Some errors are down to the server of the site you are trying to access. Other errors are often down to simple causes, such as the 400 bad request error.

The 400 bad request error is a common one that you have probably seen quite regularly. If this error does come up when you are browsing the web, you don’t need to worry. It can be caused by something very simple such as an incorrect URL being entered. This means that it can also be sorted out quickly and conveniently in many cases.

Going through a series of simple checks and steps could help to get rid of this error quickly and easily. You can then get on with accessing and browsing the website in question. This is a common error and may come up quite often if you spend a lot of time online. This is why it is a good idea to familiarize yourself with what it means and how it can be resolved.

What causes the 400 bad request error?

 

First of all, we need to know what actually causes a 400 bad request error. There are a number of possible causes, but the main one is due to entering or pasting the wrong URL. If the URL you enter has a mistake in it, this error message will come up when you try to access the site. Sometimes, depending on the web server, you may receive more specific information about the 400 error. The 400 is often followed by a number, such as 400.1 or 400.2. Some of the other possible causes along with resolutions are listed below.

How can these errors be fixed?

There are a number of steps you can take if you do get a 400 bad request error. These should hopefully get rid of the error and it shouldn’t take you long to do it. So, let’s take a look at the possible resolutions when this error comes up:

Check the URL for errors

The first thing to do is check the URL you entered for errors. One of the most common causes of this type of error is a mistake in the URL, so checking this before anything else could save you a lot of time. Rather than copying and pasting a URL, enter it manually and check that it is correct before hitting enter.

Clear the cookies in your browser

Sometimes, sites will come back with a 400 error because the cookies that are being read are either too old or they are corrupt. It is therefore well worth deleting the cookies on your browser if there isn’t a problem with the URL.

Clear the DNS cache

Another possible solution if you get a 400 bad request error is to clear your DNS cache. This is because the cause may be outdated DNS records stored on your computer. You can do this quickly and easily in Windows, and this may sort out the error.

Clear the browser cache

It is also worth clearing your browser’s cache. The error may be the result of trying to access a cached copy of the webpage that is corrupt. Although this is unlikely to solve the issue, it is still worth a try if the above methods haven’t worked.

Check the size when uploading files

Sometimes you may see the error appear when you are trying to upload a file to the website. If this is the case, there is a good chance that the file you are uploading is too large. When the file is too big, it may be rejected by the server and this then produces the 400 error.

Checking your computer or internet connection

If you find that the error is occurring on all or most of the websites you are trying to access, it is probably an issue with your computer or your internet connection. You should, therefore, conduct a speed test on your connection and also check with your Internet Service Provider.

See if there are problems at the other end

As I mentioned earlier, errors like this are not always at your end. It could be something to do with the site you are trying to access. Therefore, if you can, try and get in touch with them to find out whether it is something that they need to resolve. They can then work on fixing the problem, which will make it accessible again. There are a number of errors that will not be resolved on your side. This includes the 401 Unauthorized error and the 403 Forbidden error.

Hopefully, one of these methods should help to identify the cause of the error and solve the problem. If you are still getting the error, it is worth getting on with something else and then returning to the website, later on, to see whether it has resolved itself. Just keep trying the site periodically and you may find that, eventually, you manage to access it without the error.

Conclusion

So, there is no need to panic if you do come across a 400 error when you are surfing the web. As I’ve explained, more often than not it will be something perfectly simple that is causing the problem. In some cases, it will even be an issue on the other end. Resolving it should not take a lot of time, although you may need to try a number of the steps above to get there. With any luck, the first step (checking the URL for errors) will sort the problem out. However, if it doesn’t make sure you try the other steps before you start to panic.
