OK, deal!
I gave a ping here in webmail.semprevivapresentes.com.br, the same is correct with the one of locaweb!
Before using easyengine, I did everything in hand, I was using this tutorial https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16 -04
The same has this piece of file,
... add_header Strict-Transport-Security "max-age = 63072000; includeSubdomains"; ... I removed the "includeSubdomains" and worked fine, but I did not find this file with easyengine
