Sometimes you get a page containing some type of error code instead of the web site you expected to see on your screen. Below is a list of the most common error codes and what they mean.

  • 400 - Bad Request - This error code is telling you that the request could not be understood by the server due to some type of grammer or spelling error contained within the link on a web page.

  • 401 - Unauthorized - This error code means that the creators of that web page have given only certain people authorization to visit it. For example, an online college course web page.

  • 402 - Payment Required - This error code gives a specification of ways to pay the fee required such as entering charge card information.

  • 403 - Forbidden - This error code appears when the server does not wish to reveal exactly why the request has been refused, or when no other response is applies. Not even authorization will help here.

  • 404 - Not Found - This error code is one of the most common you will see appear. This usually means that you have mistyped an URL address in the address bar, and also you want to double check to see that you are using the forward slash (/) and not the backward slash(\) as well.

  • 405 - Method Not Allowed - This error code appears when the method being used to access the web page is not allowed for the resource identified by the request. An "http" address is only one of the methods to access web sites, and the most commonly used. A "ftp" which is a method to upload information on the Internet may be a example of a server that recognized "ftp" clients.

  • 406 - Not Acceptable - This error code appears if the server is only capable of generating response entities such as spam e-mails, who do not receive requests, but only send mass mailings.

  • 407 - Proxy Authentication Required - This error code is similar to a 401 Unauthorized error code , but instead of an authorization code you must authentication access to this server, which is a more secure way to prove you are really suppose to have access to these servers. Most companies have some sort of proxy servers in place now.

  • 408 - Request Timeout - This error code often happens when your connection to the Internet is slow, and the page takes too long to load. You can try later or earlier in the day, when your Internet connection may be faster.

There are several others that may appear, but again, the above list are the most common. If you encounter an Internet error code that you do not understand and is not on the list above, you can always use your search techniques to find what the error code means.
