This information is used to generate the server's digital signature and is sent Probably you are using Full (strict) encryption on CloudFlare, you can get rid of the problem by changing Flexible mode on your CloudFlare's SSL/TLS section – STA. This is where your lets encrypt certificate still matters (if you enable strict mode). Upgrade the gokeyless server: If you disable your domain's Universal SSL certificate, Cloudflare removes that certificate from our network and will not order or renew any additional Universal SSL certificates.
