Gitlab pages with letsencrypt - cool service, almost up but 404

Hi,

I was amazed by the functionality provided by gitlab.com, cool stuff. Just as a playground I set up a gitlab page - i think the repo content should be visible to everybody.
https://gitlab.com/itsmee/itsmee.gitlab.io

External URL works and I’m able to ingest the well-known via gitlab-le. However, independent on where i place ith with the path (/public/.well-… | /_site/.well- | /.well- …) - I’m only able to get a 404 response from Gitlab Pages. I’m sure its me, e.g. with a incomplete .gitlab-ci.yml entry. However, I’d appreciate some poke into the right direction…

gitlab-le --email “mail” --domain itsmee.de www.itsmee.de --repository https://gitlab.com/itsmee/itsmee.gitlab.io --token “token” --path _site/.well-known/acme-challenge/ --jekyll
