Automad and WonderCMS not actually public?

My YunoHost server

Hardware: Old laptop or computer
YunoHost version: 11.2.12
I have access to my server : Through SSH | through the webadmin | direct access via keyboard / screen | … all the above
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no special context
If yes, please explain:
If your request is related to an app, specify its name and version: WonderCMS version: 3.4.3~ynh1; and Automad version: 1.10.9~ynh5

Thanks for any help on this!
