Description: There a problem connecting to the Internet.

Solution: Most Internet connection problems are temporary, so the most common solution is to wait a while and then try again.

If the problem persists, check to see whether the operating system and other programs can access the Internet. Also check the availability of Microcosm servers (www.microcosm.co.uk and www.microcosm.com) using ping and/or a web browser.

On Windows, the extended error code is the error code returned by the operating system when the connection failed. Refer to Microsoft's documentation for the meaning of this code, which may help to diagnose the cause of the issue. On macOS and Linux the extended error code is usually a system error code relating to the connection failure, but not always.

If you are running a shell-protected Windows DLL then you can get error 745/12019 (or error 745/5023 for SDK versions 8.0 and higher) if you are using it with a Software Key. Unfortunately both types of Software Key are not compatible with shell-protected Windows DLLs.

An example of some extended errors under Windows include:
12007 - the Microcosm server name could not be resolved. Try rebooting the router.
12175 - the OS failed to perform content decoding on the server response. In this case the user will need to update their OS to that it uses the latest version of TLS to communicate with our website.
12037 - certificate has expired. This could occur if the user is running an old operating system, e.g. Windows XP, which has root certificates which have expired. In this case they should update the root certificates.
