Hi, it seems that the only subdomains that work are:
*.speedsatoshi.com
e.g:
www[DOT]speedsatoshi[DOT]com WORKS
dogecoin[DOT]speedsatoshi[DOT]com WORKS
Root domain and sub-subdomains do not WORK.
speedsatoshi[DOTcom DOES NOT WORK
www[DOT]dogecoin[DOT]speedsatoshi[DOT]com DOES NOT WORK
It seems you didn’t bother to visit the subdomains. I get a page not found error (404). Also, what you posted does not explain why the root domain is also not working.
An HTTP 404 error is a client side error that means that the origin web server couldn’t find a requested file. Cloudflare does not generate 404 errors, so this would indicate something is not configured correctly at your hosting provider. It’s possible that a document root with your origin is pointed to the wrong host name or different working directory.
You should be able to find these errors 404 in the access logs of your origin web server.
The best next steps would be to work with your hosting provider to identify what potential misconfiguration could be in place that would cause the origin to look for a file where it doesn’t exist.
