every time i go on minetest.net and click download it says The requested URL could not be retrieved

While trying to retrieve the URL: http://minetest.net.alias/

The following error was encountered:

Unable to determine IP address from host name for minetest.net.alias
The dnsserver returned:

Name Error: The domain name does not exist.
This means that:

The cache was not able to resolve the hostname presented in the URL.

".alias"?

http://minetest.net/ works for me.
