ERROR

-What they mean

We have tried to assemble a list of some of the more common Error Messages and have explained what they mean and how to fix the problem.
The descriptions in this particular section are a lot more detailed than the other error articles, and generally provide a specific action that should remedy the fault.

The other articles contain a full listing of all error messages and simply have a brief translation from Error code to English.

To quickly find the answer you were after, you can press CTRL F and enter your message.

Obviously, if you can't find an explanation or don't understand the one we have written, please don't hesitate to email me mithiverma14@gmail.com




400 - Bad requestExplanation
There's something wrong with the URL (Uniform Resource Locator) you typed. This can be caused by one of the following:

* The server you're contacting doesn't recognise the document you're asking for

* Your browser doesn't support the form you're trying to access

* It doesn't exist

* Not authorised to access it

Solution

Check the spelling of the URL. Pay special attention to uppercase and lowercase letters, colons, and slashes.


There may be a problem with that document. Send a message to the site administrator. Normally 


401 - Unauthorized Connection refused by hostExplanation
This error will usually occur, when an Internet site is protected, and the server didn't receive the correct password for entry.

Solution

If you are registered with the site, you could try entering your password again if you have the opportunity. As with URLs passwords are often case sensitive, so type the password carefully.

If you aren't registered, but think you're eligible for one, contact the site's Webmaster and ask for it.

Some sites also put a block on domain types--if you're not from a .gov or .edu domain, for example, you may not be able to gain access.


403 - ForbiddenExplanation
This error will usually occur, when an Internet site is protected and the wrong password was entered.
It could also mean that the server isn't properly configured.

Solution


If you are registered with the site, you could try entering your password again, if you have the opportunity. As with URLs, passwords are often case sensitive, so type the password carefully.

If you aren't registered, but think you're eligible for one, contact the site's Webmaster and ask for it.


Some sites also put a block on domain types--if you're not from a .gov or .edu domain, for example, you may not be able to gain access.


404 - Not Found or File Not Found Unable to Locate the ServerExplanation
This means that the document you've requested no longer exists in its original location. This could be because:
* Document has been moved to another location on the server

* The URL may have been mistyped

* Has been removed entirely from the system

Solution

Try carefully retyping the URL, paying particular attention to capitals and making sure there are no spaces.

Try going one level up, by deleting the portion of the URL that follows the last slash, to see if the site is live. If it is, check to see if there are links to the document you were looking for. Failing that, you could delete the last slash and type .html instead and see what that gives you.

It may also mean that this site doesn't exist any more.


500 - Internal ErrorExplanation
The server was unable to send the HTML document, due to an internal (server software) error. An improperly configured server causes this.

Solution


Contact the site's administrators and tell them to fix it


501 - Not ImplementedExplanation
The server doesn't support the feature you have requested.

Solution

Don't request it?


502 - Service Temporarily OverloadedExplanation
This error indicates that the server is experiencing high-traffic load and can't process the request.

Solution

You can often access the site by trying to reload it. If the error persists, you may want to try again later.


503 - Service unavailable or Gateway TimeoutExplanation
One of your settings (Gateway) is wrong.

Solution

It is fairly unlikely that you will get this error, if you do, contact the administrator, or even the ISP, as it's a fairly big problem (tm)


You can't log on as an Anonymous UserExplanation
This error message appears when you try to access certain FTP sites.

*It indicates that the site allows access only to registered members

*The site may only allow access to a limited number of non-members, in which case the site is simply busy

*Your browser may not support anonymous FTP access

Solution

You can try to access the site again later, or if you're a registered member try entering your User ID and Password manually using FTP software package.

Too many users Network Connection was refused by the Server Too many connections--try again later
Explanation

No site has unlimited access: physical connections or administrator policy allocate a number of anonymous users to a given site. When that number is exceeded, all who try to log on, receive this message. This error frequently turns up when you try to connect to a busy FTP software site that can't generate its own error messages.

Solution

Just keep trying until you get lucky. However, on a busy site (like Netscape's the week after a big announcement) or one with very limited access rights, you may be out of luck. If so, check to see whether the site has mirror sites, and try one of those.


Cannot add form submission result to bookmark listExplanation
You have just entered a search request and tried to save the result as a bookmark. Though it may appear as a discrete address, the result isn't a legitimate URL, so you can't add it to your bookmark list.

Solution

Try using the 'Save As' command from your browser, then add the saved page to your bookmark list. Depending on the CGI/asp/php etc script behind the query, you may or may not be successful. You never know, it could be worth a try.




Host unavailableExplanation
The 'Host Unavailable' error occurs when the host server is down. This could possibly be for maintenance.

Solution

Hit the Refresh or Reload again. But wait a while between refreshes.




File contains no dataExplanation
The site you've accessed is however the right one, but there are no Web page documents on it. You may have stumbled upon this site just as updated versions are being uploaded.

Solution

Try the URL again, carefully. If that doesn't help, try again in an hour. You could also sometimes by-pass this error by re-typing the URL with a :80 before the last slash. For example www.sitepointforums.com:80/




Helper application not foundExplanation
Your browser didn't recognise a file at the Web or Net site you visited. Most browsers can be extended using helper applications (or viewers) to read files they don't otherwise recognise. These files aren't necessarily graphics--they can be sound files, movie clips, or ZIP or SIT archive files you're trying to download.

Solution

The dialog box that carries this message will usually give a clue about the file type that's missing. (You may see some gibberish about octet streams, but after that you'll probably see some reference to graphic-TIFF, which gives it away.) Look at our help for your computing platform (Windows, Mac etc) for viewers for the most common file types. Then follow your browser's instructions for assigning a viewer for each file format that you wish to view online.

NNTP server error
Explanation

You're trying to log on to a USENET newsgroup, but you can't get to it. The Usenet server is one of the services that most ISP's provide; however they can't subscribe to all the newsgroups in the world, so it may be that this newsgroup isn't available.

Solution

Make sure you've typed the URL correctly. If that doesn't help, You could let them know that you would like it enabled, and they may then look into making this available, provided there is enough interest from other people.




Permission denied

Explanation
This error message occurs when your are trying to upload a file to an FTP site. The error indicates that the site will not allow the upload, the site is too busy, or you have typed the wrong URL.

Solution

Check the spelling first and type it again. If the error message reappears, try again later. If it persists, send email to the Webmaster and ask how you can upload a file to that site.


Host UnknownUnable to Locate HostExplanation
These errors will occur for one of the following reasons:
* The host server is down for maintenance,

* You typed the URL incorrectly.

* You've lost your Internet connection

Solution

Hit the Reload/Refresh button. This is often a temporary problem with the Net. Check the URL for any spelling mistakes (and don't forget case-sensitivity), then make sure you're connected by hitting Reload/Refresh, which will re-establish connections in many cases.


Viewer not foundHelper Application not foundExplanation
Your browser doesn't recognise a file at the Web or Net site you're visiting. Viewable files aren't necessarily graphics--they can be sound files, movie clips, ZIP or SIT archive files, and so on. If it's not a GIF or JPEG file, your browser may not know what it is.

Solution

Save the file to disk and then get the application called for by it. Setup in the browser Helper section is required to make it work
The dialog box that carries this message, will usually give a clue about the file type that's missing. (You may see some gibberish, but after that you'll probably see some reference to graphic-TIFF, which gives it away.) Then just follow your browser's instructions for assigning a viewer for each file format that you wish to view online.


Failed DNS lookupExplanation
The domain name system (DNS) can't translate the URL into a valid Internet address. This is either:

* A harmless blip

* The server that you're trying to connect to may be overloaded with traffic or temporarily down

* The result of a mistyped URL (specifically, a mistyped host name).

* If you're accessing the Internet via a modem and you get a DNS error for each Web Site you try to access, chances are something is wrong with your connection.

Solution

* Blips in DNS lookup can be fairly common, and often you can rectify this by clicking the Reload/Refresh button. If that doesn't work, check your typing of the URL carefully. If the problem persists,

* You could also try re-launching your browser and your required communications software. If the problem persists, contact your ISP and they can talk you through some other options.

* Unfortunately, there's no easy way for you to tell whether a server is down or just busy. Try again after an hour or so.


Please check your username and password and try againExplanation
Username Password is wrong

Solution

If you can't connect because your password is not working, double check that you are typing in the letters EXACTLY as shown on your signup sheet. All usernames are in lower-case and passwords are case sensitive.
The most common password problem is the CAPS LOCK key being on Also, make sure you are not using your e-mail login name and password. If you have tried all of this, please call the helpdesk and we can re-set your password.
