I am trying to install cloudflare origin CA on AWS EC2 as mentioned here

  1. https://support.cloudflare.com/hc/en-us/articles/115000479507
  2. https://support.cloudflare.com/hc/en-us/articles/217472077
    now where i am stuck is should i have to enable ssl/tls on my AWS instance as mentioned here:
    https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/SSL-on-an-instance.html#ssl_enable
    or
    should i just ignore it and go the cloudflare way ?
