If I hit the correct site, on the SSL/TLS app, turn on Always use HTTPS and turn on Automatic HTTPS rewrites. That will first ensure users always end up on https and will correct some http calls. But, it looks like you have a script being called with http, that will need to be manually updated as automatic rewrites won’t help with script or css calls.

Beyond that, I don’t see the 521, perhaps check logs and make sure Cloudflare IPs are white-listed?
