Installation of Letsencrypt SSL on Bitnami Stack

Hi Guys,

I am trying to install the Letsencrypt free SSL on my test server but I am getting a problem with the automatic validation of the server is failing and I think it might be due to the way CodeIgniter server the document root. 

As per the doco here: https://docs.bitnami.com/general/how-to/understand-bncert/#certificates-not-renewed-automatically

It mentions to create a new folder and then map it to the wep server. I have done that but when I test it from the front-end I get the infamous error message:

"You don't have permission to access /.well-known/ on this server."

Hence, I don't believe Letenscrypt will be able to validate my domain.

How can I serve a folder outside the document root via CodeIgniter for validation purposes?

Kind Regards
Trent
