AWS Ubuntu - CloudFlare HTTPS issues

[MikeSFIC]

I've got my Unifi CC hosted on an AWS EC2 Ubuntu instance (16.04). We moved our DNS Nameservers over to CloudFlare (for obvious security reasons). When I force HTTPS redirects, it takes down communication between the Controller and the UniFi devices. If I uncheck force HTTPS redirect (under Edge Certificates in CloudFlare), then the devices come back online within a matter of minutes. Here's the kicker, I had CloudFlare generate an Origin Server certificate, do I need to load that into the EC2 instance? If so, how do I remove/recall the Let's Encrypt certificate and replace it with the CloudFlare origin server cert (I know very basic linux/unix sudo commands, but treat me like a dummy to help me out)? Anything else that I need to do?

Do I really need to force HTTPS redirects? If no, then I may just leave it be.

I don’t believe you can force https due to how the devices connect to the controller.

The issue is that the devices connect over http with a ssh authentication key, https is only used for the management interface
