What is HTTP Errors
This is a list of Hypertext Transfer Protocol (HTTP) response status codes. Status codes are issued by the server in response to the client’s request made by the server. This includes some additional code used in IETF Request for Comments (RFC), other specifications, and some common applications of HTTP. The first digit of the status code designates one of the five standard classes of responses. The message phrases shown are specific, but any human-readable option may be provided. Unless otherwise stated, the status code is part of the HTTP / Standard
The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.
Microsoft Internet Information Services (IIS) sometimes uses additional decimal sub-codes for more specific information, although these sub-codes only appear in response payloads and documentation, instead of actual HTTP status codes No.
HTTP visitors can be a big frustration for website visitors. We all have experienced them ourselves and know first hand how annoying it can be to browse a website and then BAM! You hit a wall with an HTTP error.
These errors are messages from web servers indicating that something has gone wrong, and some specific types that are most common:
401 (Unauthorized) ⇒ This error occurs when someone tries to access a page for which they are not authorized. You can usually fix this error by reviewing the URL of the page that is causing the error; It is possible that the link clicked is only for authorized users (for example, users who have a login with a valid user ID and password).
403 (Forbidden) ⇒ This error occurs when a server will not fulfill the request because a user is not allowed to use something slightly different from a 401 error, a 403 error assuming the user logs in with a valid user ID and password These may occur, but do not have authorization to access the specific page. Typically, this means that the user has access granted by the website administrator.
404 (not found) ⇒ This error is one that most people see regularly, unfortunately. A 404 error occurs when a user tries to access a webpage that does not exist (or is no longer). This error can result in broken links, incorrect URLs, or redirected pages that are no longer valid. This error can be easily fixed, however, by reviewing crawl errors in your Google Search Console, and redirecting broken links to these errors in WordPress or other content management systems, or to your web developers Can add to your redirect.
500 (Internal Server Error) ⇒ This error is certainly the most common error seen, and is a very common error message for any type of internal server error that cannot be easily defined. This error can usually be fixed when the user refreshes their web browser (if the error is busy due to the server and is unable to process requests quickly), deletes their cookies, or Goes to the page at another time, possibly when the server isn ‘t therefore overloaded. On your end, however, you can usually troubleshoot the cause of the error through your WordPress or content management system, and follow the steps to diagnose and fix the problem.
504 (Gateway Timeout) ⇒ Another common, 504 error indicates a gateway timeout, which occurs when one server did not receive a timely response from another server when it was attempting to load the page. Most of the time this problem is not the fault of a website, but there are some ways to troubleshoot the error. If this is the result of a corrupted database and your website is on WordPress, you can install and run WP-DBManager to repair and optimize your database. This can also be a problem with your .htaaccess file within WordPress. Or you can try contacting your hosting company to see if the problem is on their end.
