Lets encrypt problem on fresh installation

Hi, I’m having problems with lets encrypt in my new installation.
I can only access through IP and also through www. But when accessing without www, it redirects me to https and it does not work, it’s as if it was not active.
the domain is www.foro.chilere.com.py
It is accessed without problems. but without the www it gives error.
Also when trying to rebuild using ssh, nothing works. I’m using the digitalocean oneclic app
