HTTP status codes are three-digit codes, and are grouped into five different classes. The class of a status code can be quickly identified https://www.onehippo.org/library/concepts/error-pages-and-error-handling/1.-handling-error-codes-and-exceptions-by-the-web.xml.html 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 https://www.digitalocean.com/community/tutorials/how-to-troubleshoot-common-http-error-codes 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 error, means the HTTP request that was sent to the server has invalid 3 503 Service Unavailable 4 Understanding and Fixing 502 Bad Gateway Errors 5 How to Fix a 404 Not Found Error About.com About Tech PC Support . . .
