Check Your DNS Settings.
If you’re having trouble loading pages on your website, check your DNS settings first. This is the system that translates domain names into IP addresses so that computers can find each other online.
Check Your Server Configuration.
Next, make sure that your server configuration is set up correctly. There are several things that need to be checked here, such as whether your web host has enabled caching (which speeds up site load times), whether your web host has properly configured the file permissions, and whether your web host has disabled directory browsing (which allows users to browse through directories).
Check Your Hosting Provider’s Support Page.
If you’re having trouble loading pages, check your hosting provider’s support page first. It might say something like “Your website is not responding.” This means that there is an issue with your server configuration.
Check Your Webmaster Tools Account.
If your site isn’t loading properly, you’ll need to contact your web host. They should be able to help you fix any issues.
Check your security
It’s also possible that your site has been hacked. This means that someone else has taken control of your website and is using it to send spam emails or sell counterfeit goods. In either case, you will need to contact your web hosting company to find out what happened.
