We see many error codes in our daily lives as we now rely heavily on devices like PCs and laptops and make the most of the Internet.

In this article, we will will discuss the worst error codes and how to fix them:

1. Error 404 Not Found

This is the most frequently occurring error code we often encounter. When we find a link, click on it, or type a website URL, we sometimes get a 404 error. This is because the URL has been changed or removed. Another reason for this error may be that we have typed a website URL incorrectly, the network connection is unstable, or the domain name is missing. Error 404, however, is not always an invalid code. For various reasons that cause this error, there are many ways to fix this problem again, but it not always can be fixed.

Some of the ways to fix this problem are:

• Sometimes, it can be a network problem, so it can be easily fixed by reloading the page or updating it, as it reconnects and the website is successfully launched.
• If the URL is handwritten, it needs to be checked again, as a single mistake in the missing word or characters can cause error 404. The URL should therefore be spelled correctly.
• If the website is accessible from any other device and not from your own, it is your fault device. Try clearing or clearing caches and cookies and restart the website.

2. Error 503: Service Not Available

This error means that the requested web server is unavailable. Error 503 is also temporary, but this may interfere with our work when it occurs at the worst possible time. When web servers are overcrowded and overloaded by users, this error is common if not properly maintained. This error also occurs when the web server is down with some internal fixes. There are many HTTP status codes, so it is not easy to find the real cause of the error.

If this error occurs several times on the same website, administrators access the web server and fix the problem while returning the 503 error to waiting users. Managers are given access, but all other traffic must stay until the web server storage is complete. This error mostly comes from the server-side, so users are limited in troubleshooting options without the website owners taking immediate action.

3. 400 Invalid Request Error

This error is caused on the client-side, and the server will not allow it to proceed until the error is fixed. An error of 400 indicates that the server will not process the request requested by the customer. Probably because the application was poorly constructed, deceptive or invalid. Some of the main reasons for this are incorrect URLs, including invalid characters, corrupt cache, and cookies if the file size is too large, or the generic server error.

Some of how this error can be corrected are as follows:

• By checking the URL for authenticity, it adds too many characters, and some are illegal and unacceptable. Therefore, it needs to be thoroughly tested before applying.
• Storage and cookies may be other criminals that cause the problem. Browser cache and cookies should always be deleted before you can request re-access.
• If the file uploaded exceeds the server limit, we should reduce the file size before re-uploading. This can be another way to fix the problem.

4. Error 401 is not authorized

This HTTP status code determines that it has received an unconfirmed request. This is a client-based error. By default, it means the server will not allow us to log in unless we enter a valid user ID and password. This error appears most frequently on password-protected pages and denies access unless authentication credentials are properly submitted. Some of the other reasons for Error 401 could be a firewall problem or an invalid URL.

Some of how this error can be corrected are as follows:

• Sometimes, clearing the firewall and browser cache and cookies will fix the problem.
• Since a website needs authentication, it sometimes logs in and logs in and fixes the problem.
• URL testing is another important requirement, as all characters are important and need to check whether the site is out of date or not.

5. 500 Internal Server Error Error

This error is one of the most common errors that occur on a website server. We cannot fully comprehend the real cause and why and how it happens, but this, like all other errors, needs to be corrected immediately.

The 500 Internal Server Error can be caused mainly by a temporary glitch or a website program. Sometimes the long run of this error negatively affects SEO.

We may fix this issue by refreshing the page or returning later or clearing the browser cache and cookies.
