Comment (by Ipstenu):

 From #38161

 > Using something like  {{{substr( home_url( '', 'http'),7)}}} might be a
 suitable substitute when $_SERVER is unavailable. (If there's a better way
 to get a site's hostname than slicing up home_url() that of course would
 work too.)

 We'd want to use parse_url() I think, since https is everywhere. Also some
 people use WWW and some don't :/
