Website common Error.

Sometimes when you try to visit a web page, you are met with an HTTP error message. This is the message from the web server that something went wrong. In some cases it may be a mistake you made, but often, it is the fault of the common error

Each type of error has an HTTP error code dedicated to it. For example, if you try to access a non-existing page on a website, you will complete the familiar 404 error.

Now, you might wonder which ones are the most common HTTP errors during web surfing? This is the question we will answer in this article.

401 Unauthorized(website common error)

The HTTP 401 Unauthorized client error status response code indicates that the request has not been applied because it lacks valid authentication credentials for the target resource.

This status is sent with a  header that contains information on how to authorize correctly.

This status is similar to 403, but in this case, authentication is possible.


400 Bad Request

The HyperText Transfer Protocol (HTTP) 400 Bad Request response status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing)


403 Forbidden

A server that wishes to make public why the request has been forbidden can describe that reason in the response payload (if any).If authentication credentials were provided in the request, the server considers them insufficient to grant access. The client SHOULD NOT automatically repeat the request with the same credentials. The client MAY repeat the request with new or different credentials. However, a request might be forbidden for reasons unrelated to the credentials.

An origin server that wishes to “hide” the current existence of a forbidden target resource MAY instead respond with a status code of 404 Not Found.

404 Not Found

The HTTP error 404, or more commonly called “404 error”, means that the page you are trying to open could not be found on the server.This is a client-side incident which means either the page has been deleted or moved, and the URL has not been modified accordingly, or that you have misspelled the URL.

408 Request Timeout

The following messages are also client-side errors and so are somewhat related to the 408 Request Timeout error:

501 Not Implemented

The 501 not implemented error indicates that the server does not support the functionality required to fulfill the request. This is the appropriate response when the server does not recognize the request method and is not capable of supporting it for any resource, response is also cacheable by default.

Due to the various browsers, web servers, and operating systems, a 501 not implemented error can present itself in a number of different ways. But they all have the same meaning. Below are just a couple of the many different variations you might see on the web:

  • “501 Not Implemented”
  • “Error 501”
  • “HTTP 501”
  • “HTTP Error 501 Not implemented”
  • “The server either does not recognize the request method, or it lacks the ability to fulfill the request.”

502 Service Temporarily Overloaded

A 502 Bad Gateway Error means that the web server you’ve connected to is acting as a proxy for relaying information from another server, but it has gotten a bad response from that other server. It’s called a 502 error because that’s the HTTP status code that the web server uses to describe that kind of error. These bad responses could be due to a number of different causes. It’s possible the server is overloaded or there are network issues between the two servers, and it’s just a temporary problem. It’s also possible there’s an improperly configured firewall or even a coding error, and that the problem won’t get fixed until those issues are addressed

  • HTTP Error 502 Bad Gateway
  • HTTP 502
  • 502 Service Temporarily Overloaded
  • Temporary Error (502)
  • 502 Server Error: The server encountered a temporary error and could not complete your request
  • 502 Bad Gateway Nginx

503 Service Unavailable

The 503 Service Unavailable error is an HTTP status code that means the website’s server is simply not available right now. Most of the time, it occurs because the server is too busy or because there’s maintenance being performed on it.

Connection Refused by Host

The message ‘Connection Refused‘ has two main causes: Nothing is listening on the IP:Port you are trying to connect to. The port is blocked by a firewall
