I have a situation currently where i need to enable HSTS from Cloudflare.
Currently the setup is as the following:
Cloudflare CDN passing the traffic to on-premise Load Balancer, the Load Balancer virtual server is running on port 80 (HTTP), which is a non-HTTPS protocol.
My question here, if I enable HSTS from Cloudflare-level, forcing connections to be HTTTPs from client side, will that result to an error since the on-premise host is running on port 80?
Appreciate any inputs to the above situation.
