You got me there, Horizon.
1. Protocol:HTTP + HTTPS
2. Configure, General, Advanced parameters, Exclusively serve on HTTP. Virtual path: /
Thank you very much
Exclusively Serve On HTTPS: If a request's virtual path matches with one of the paths or the patterns declared in that table, and if the request was received on a non-secure (HTTP) connection, the server generates a redirection to the same virtual path but using HTTPS to force it to be served on a secure connection. The Exclusively Serve On HTTPS table is available only when the current host's Protocol is set to HTTP+HTTPS.
