Lets Encrypt issue

I am trying to get a lets encrypt certificate via the Yunohost admin panel for my domain courtguinness.nohost.me, but the system will not let me do it.
Does anyone have any ideas?

Hi there,

the little diagnostic sometimes mislead yunohost into thinking the domain is not properly configured :s

If you properly checked that your domaine is available through HTTP via the domain name, then you can also install the lets encrypt certificate via the command line :

yunohost domain cert-install your.domain.tld --no-checks

Thank you
I will try this shortly
