Tried AutoDevops, got "default backend - 404"

I went all steps on instruction provided by GitLab https://docs.gitlab.com/ee/topics/autodevops/quick_start_guide.html : created project from HTML template, added Kubernetis cluster, enabled auto devops, set base domain to 35.223.128.134.nip.io (is it correct?) but this thing shows me error “default backend - 404”

http://35.223.128.134.nip.io

what am i doing wrong?
