Subdomains Shutting Down

My website URL is:
http://r-deseretgear.risenup.icu/

What I’m seeing is:
this site can’t be reached

I’m using this software:
WordPress

Additional information:
It has happened twice now, I’ve spent probably about 30 minutes customizing my subdomain on WordPress, then out of the blue my subdomain just shuts down and I can no longer interact with it at all.
