Question

GitLab

Greetings. I have a group, in a group subgroup, subgroup project. Where to knock on pages?
Tried: http://groupname.gitlab.io/subgroup/project and http://groupname.gitlab.io/project and http://subgroup.groupname.gitlab.io/project.
yml file is default for html. layout project.
When I sawed the project not in a group, at home, everything was ok. http://mylogin.gitlab.io/project worked.
