I have bought a domain on godaddy. The Cloudflare name servers have been added to the godaddy domain. The website is running on an EC2 instance using Elastic BeanStalk.
This is working fine except for getting all traffic to route through https all the way through to terminating at the EC2 instance.
I have created an origin certificate on Cloudflare and setup a config file in ebextensions as specified in aws doco: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/https-singleinstance-php.html
After turning on Full (strict) encryption mode in Cloudflare, I get the error code 521 and cannot see the website. Changing it back to Flexible mode fixes it.
As a side note I can’t access the godaddy Cpanel to upload the certificate. Not sure if that has anything to do with it. The godaddy cpanel button doesn’t exist…
