URL Checker Error Messages
If URL Checker encounters an error, it reports the type of error it found. In the report, three-digit error codes are standard HTML error messages. Consult your system administrator or any online reference for details about errors such as:
Not Found (404)
In addition to reporting HTML error messages, URL Checker generates the following error codes:
- Connection Refused (-1)
- The Web server's host computer was found, but the host computer refused to accept the connection on the default port. This usually indicates a problem with your Web server software or that the Web server software is not running.
- Malformed URL (-2)
- The request could not be understood by the server due to malformed syntax.
- Host Not Found (-3)
- The URL included content the system could not parse.
- Connection Timeout (-4)
- A connection could not be established within a predetermined, set time. This usually indicates a problem with your routers or firewall, a Web server hardware failure, or general Internet connectivity problems.
- Host Unreachable (-5)
- The host name is invalid.
- Timeout (-6)
- The client could not establish a socket connection within the time that the server was prepared to wait. The client can repeat the request without modifications at any later time.
- Network is unreachable (-7)

- Item not available (-18)
