I've just created a space on the Digital Ocean cloud.
To enable CDN, it asks for an SSL.
My domain manager is Cloudflare.
I've created a CNAME on the Cloudflare DNS settings page.
Then created an origin server SSL certificate and added those keys to the Digital Ocean subdomain settings page.
But I'm getting this error when I'm visiting the URL.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
How can I fix this issue?
Use SSL certificate for your original domain then it will work. Don't use a certificate generated by Cloudflare, because that is for something else that Cloudflare side use for to enable strict policy in their side.
