Issues with Your Hosting
An issue with your site’s name server
Make sure the name server for your domain or subdomain is properly directing the ads crawler to your content. For this purpose, you can contact your hosting providing company immediately to get this problem resolved.
There’s an issue with your site’s server
Sometimes when the ads crawler tries to access site content, the site’s server is unable to respond in time. This can happen because the server is down, slow or overloaded by requests.
We recommend ensuring your site is hosted on a reliable server or by a reliable service provider.
