HTTPS Error 521, Universal SSL Cloudflare

I have free Universal SSL with CloudFlare. I wanted to set up a permanent SSL redirect on my website. I change A-name to IP my droplet on digitalocean and when i try to use https-protocol i get error: 521 (ssl handshake filed) and loop

I think, that is necessary to change standart settings in configuration apache2, but what to change and where?

Previously, I used shared hosting by godaddy and never encountered this problem. Please help me!

Just adding a new answer here: when you by pass the https request on the node balancer, add the origin certificate to the load balancer, and make sure it’s selected. That way, you can still use strict CF connections.

Hope this helps.

problem solved! Change SSL = full to Flexible

If you require FULL SSL, you should make sure that your SSL works even without CF through
