Many Webmasters wanted to publish subsites for other contents,–rather setting up a directory-based subsites, but these subsites what you’ve trying to implement needs some little work via any web-hosting service. It’s easier to use these subdomains because, it can be easy for your visitors to jump from one tsite to the another,–without needing to register for multiple domain names. For this instance, you wanted to have a support center for your site, but you experienced an issue with subdomains because, you discovered an error page via any cable provider. This is common,–due to a missing configuration with your control panel on your hosting controller.
