We just now this very second finished configuring our second bare metal machine and setting up the awesomeness which is Cloudflare Load Balancing.
Problem: www resolves fine and load balancing does work when Proxying is disabled. When we go to enable proxying, www reports a Cipher mismatch in our certificate.
We tried disabling SSL altogether, waited an hour to ensure TTL was met, but www never resolved. As soon as Proxying was re-disabled, www started resolving again.
Our individual hosts are running NodeJS backends reverse proxied through Nginx, with our wildcard certificate on each www host, then CF load balanced by region.
Are we in need of some configuration in Nginx to handle Cloudflare’s proxying?
