General Information

HTTP - If your viewers cannot access your website, your Host's server may display a page in the browser with a numerical Error Code that represents the reason why the page cannot be viewed.

FTP - Sometimes, when FTP Publish is unsuccessful, you may see an Error Code in the FTP window. These Error Codes are sent by the FTP server to inform you of what occurred.

These HTTP and FTP Error Codes are usually WWW Standard Server Response Codes. However, the Error Code seen may not be a WWW Standard Server Response Code. Your Host may use non-standard HTTP and FTP response codes or the Host may use HTTP response codes in place of FTP response codes.

In ALL cases, HTTP and FTP errors are the result of an error(s) by the Host, the user, the ISP or the local or wide area network.

Examples:

Host Error - server congestion, server unavailable, etc.
User Error - mistyped address of webpage or incorrect Publish settings.
ISP Error - poor internet connection, network congestion.
Local Network Error - network misconfigured, firewall prevents FTP.
Wide Area Network Error - general internet congestion or outages.

Below are the standard Common HTTP and FTP Server Error Codes with brief explanations to help you troubleshoot your Website and Publishing issues.

Common HTTP Server Error Codes

400 Bad File Request - Usually means the typed address used, the url, is incorrect (e.g. uppercase letter should be lowecase letter; wrong punctuation marks).

401 Unauthorized - Server is looking for some encryption key from the viewer's browser, such as is used by banking websites for secure access to personal info, and is not getting it. Also, wrong password may have been entered. Try it again, paying close attention to case sensitivity.

403 Forbidden/Access Denied - Similar to 401, special permission needed to access the site -- a password and/or username incorrect or not entered.
.
404 File Not Found - Server cannot find the file you requested. File has either been moved or deleted, or you entered the wrong url or document name. Look at the url. If a word looks misspelled, then correct it and try it again. .

408 Request Timeout - The viewer stopped the page from loading before the server finished retrieving it. A user will either hit the stop button, close the browser, or click on a link before the page loads. Usually occurs when servers are slow or file sizes are large.

500 Internal Error - Couldn't send the webpage because of server-configuration problems. Contact site administrator or the webhost.

501 Not Implemented - Web server doesn't support a requested feature. As an example, the webserver must have expensive software on it for a website to stream certain media files such as Real Media and most web servers do not support it.

502 Service Temporarily Overloaded - Server congestion; too many connections; high traffic. Keep trying until the page loads.

503 Service Unavailable - Server busy, site may have moved, you lost your internet connection or the quality your internet connection is poor at the time.

File Contains No Data - Page is there but is not showing anything due to faulty or non standard code.

Bad File Request - Browser may not be able to load the file based on it's settings. For example, a browser has a setting to show or hide images or turn scripting on or off. If either are turned off the this error code may be seen.

Failed DNS Lookup - The Domain Name Server can't translate your domain request into a valid Internet address. Server may be busy or down, or incorrect url was entered. (The name in the address bar or in a link is converted to a numerical address by the Domain Name Server used by your ISP.) Contact your ISP.

Host Unavailable - Host server down. Hit reload/refresh or go to the site later.

Unable to Locate Host - Host server is down, internet connection is lost, or url typed incorrectly.
