im running Trilium in a Arch based distro in the 8085 port.

I have installid trilium from AUR.

I read the documentation in Trilium web, and see that i have to change config.ini in trilium-data directory but… im having trouble getting the certificate.

i try this, from lets encrypt web:

sudo certbot certonly --standalone    

and after following the several questions i get this:

Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
  Domain: xxxxxxxxxxxx.run.place
  Type:   dns
  Detail: DNS problem: query timed out looking up CAA for run.place

that is a domain i get from freenom, and it is working. So… what is the problem here? why dont like the run.place? And… what i can do to fix this?
