This error simply means that your browser is able to communicate with the website or the server you are trying to connect to, but the server or website could not find what you are looking for thus responding with https://www.maketecheasier.com/common-browser-error-messages/ a 404 error. The are many reasons like broken links, deleted or moved content, etc., behind the 404 error. But the good thing is that the error page can be easily customized in many different ways by the respective web designer or the server admin enabling them to provide alternative options to the users.Bad Gateway (502)The Bad Gateway error is not so common, but whenever you receive this error, it just means that while attempting to fulfill your request, the server which is acting as a gateway has received an invalid response from the upstream server. Most of the time, the problem is outside your computer and the error is generated due to the problems in the servers, and there is nothing much you can do to solve this problem.

You request a resource, such as web page or an image, and you get back a response, or your browser does, at least. Thanks to the "http:" https://www.globo.tech/learning-center/5-most-common-http-error-codes-explained/ you place before a URL when you type in the browser’s address bar, https://www.digitalocean.com/community/tutorials/how-to-troubleshoot-common-http-error-codes requests and responses have a predefined structure. As defined by the Hypertext Transfer Protocol (HTTP), an important part of that structure is a status code. Introducing HTTP Status Codes Status codes are three-digit numbers. A 200 code is the most common and represents a successful response. The first digit defines what is error codes known as the class of the status code. If the code starts with a 2, as in 200, that represents a successful response to the request. There are status codes that start with 1. These represent informational messages. These are rarely seen. A code of the form 3xx represents a redirection response. Typically, the browser will handle these without user interaction and get the resource browser error codes from the new location instead. Error codes come in the form of 4xx and 5xx statuses. Error codes at the 400 level mean there was a client-side error — think of something like the user typing the wrong URL in the address bar. Error codes at the 500 level mean there was a server-side error — think of something like the database server going down or perhaps running out of disk space. Five of the most popular error codes are 403, 404, 500, 503, and 504. Let’s look at each of these in a little more detail. 404 Not Found The most common error code you run into is a 404 error. The 404 status code means the requested resource is no longer available or, more specifically, just not found. Was it ever available there? You don’t know. You do know it isn’t available there now. What are some of the reasons for a 404 error? Typos are a common reason for getting a 404 error. A missing or extra letter in a typed-in url, or a wrong domain name can often result in a 404 error. Another reason for 404 errors isn’t typos; it i

HTTP status codes are three-digit codes, and are grouped into five different classes. The class of a status code can be quickly identified by its first digit: 1xx: Informational 2xx: Success 3xx: Redirection 4xx: Client Error 5xx: Server Error This guide focuses on identifying and troubleshooting the most commonly encountered HTTP error codes, i.e. 4xx and 5xx status codes, from a system administrator's perspective. There are many situations that could cause a web server to respond to a request with a particular error code--we will cover common potential causes and solutions. Client and Server Error Overview Client errors, or HTTP status codes from 400 to 499, are the result of HTTP requests sent by a user client (i.e. a web browser or other HTTP client). Even though these types of errors are client-related, it is often useful to know which error code a user is encountering to determine if the potential issue can be fixed by server configuration. Server errors, or HTTP status codes from 500 to 599, are returned by a web server when it is aware that an error has occurred or is otherwise not able to process the request. General Troubleshooting Tips When using a web browser to test a web server, refresh the browser after making server changes Check server logs for more details about how the server is handling the requests. For example, web servers such as Apache or Nginx produce two files called access.log and error.log that can be scanned for relevant information Keep in mind that HTTP status code definitions are part of a standard that is implemented by the application that is serving requests. This means that the actual status code that is returned depends on how the server software handles a particular error--this guide should generally point you in the right direction Now that you have a high-level understanding of HTTP status codes, we will look at the commonly encountered errors. 400 Bad Request The 400 status code, or Bad Request er
