Regex has evolved a fair bit since this was reported.

app/models/embeddable_host.rb

8dad778fc


      
          def host_must_be_valid
            if host !~ /\A[a-z0-9]+([\-\.]+{1}[a-z0-9]+)*\.[a-z]{2,24}(:[0-9]{1,5})?(\/.*)?\Z/i &&
               host !~ /\A(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})(:[0-9]{1,5})?(\/.*)?\Z/ &&
               host !~ /\A([a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.)?localhost(\:[0-9]{1,5})?(\/.*)?\Z/i
              errors.add(:host, I18n.t('errors.messages.invalid'))
            end
          end

I think this is resolved now?
