django subdomains error namespace does not exist

Question

Trying to configure subdomains. ie. two.example.com default domain www.example.com but getting error "app_two is not a registered namespace" via {% url 'app_two:app-two-list' %} in base.html

I've also tried {% host_url 'app-two-list' host 'two' %} but it redirects to just two and not two.example.com
