Unable to setup, Let's Encrypt

Hi everyone. I’m trying install SSL to my EasyEngine serve, but the message bellow appears:

root@mautic:~# ee site update mautic.agencialoud.com --letsencrypt
Letsencrypt is currently in beta phase. 
Do you wish to enable SSl now for mautic.agencialoud.com?
Type "y" to continue [n]:y
Please Wait while we fetch SSL Certificate for your site.
It may take time depending upon network.
Unable to setup, Let's Encrypt
Please make sure that your site is pointed to 
same server on which you are running Let's Encrypt Client 
 to allow it to verify the site automatically.

I also looked for solutions in many places, followed several suggestions but without any success

I created two A records into my zone editor to point the EasyEngine app as subdomain (mautic) as we can see

A RECORDS:

mautic.agencialoud.com. 	14400 	IN 	A 	159.203.176.69
www.mautic.agencialoud.com. 	14400 	IN 	A 	159.203.176.69

Both of records are already pointing to server IP (159.203.176.69) as we can see in this link: https://www.whatsmydns.net/#A/mautic.agencialoud.com

Someone has any other suggestion to me?

PS: I don’t have CloudFlare or any other kind of service like these

It doesn’t look like that subdomain is publicly accessible, e.g.

> http://dnscheck.pingdom.com/?domain=mautic.agencialoud.com
> http://leafdns.com/index.cgi?testid=8DD3DBF7

Would I would do is point A record of mautic.agencialoud.com to 159.203.176.69 and then do a CNAME for www.mautic.agencialoud.com that points to mautic.agencialoud.com.

At least that’s how I set up my DNS for Let’s Encrypt.
