There's something wrong with your web site. That's all we can tell you from that information.

i use from free host.
Could it be for this reason

Better contact the hosting provider, maybe they can tell what has changed or is not working properly anymore.

If you can get on the server you need to browse the site locally and you will see the error message. You might be able to check IIS logs and see more also.

What the error you are getting is telling you is that the custom error page is not setup properly.

Do you have robust error reporting and logging in your backend VB code?
