ERR_SSL_VERSION_OR_CIPHER_MISMATCH on Digital Ocean

Question

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.

This worked for me. I used ZeroSSL to generate the certificate instead of the Cloudflare origin certificate generator. – Chamupathi Gigara Hettige Dec 24 '20 at 11:15
yes, free SSL sites work with some limitations like validity if you need more need to pay for a wildcard SSL certificate. – Vikum Sanjeewa Dec 24 '20 at 11:17

Submitting the CNAME in App Platform before adding the record in the DO networking tab causes App Platform to register the domain with CloudFlare before it exists. There is a 30 minute TTL on this record then your domain will start working.

However, as a workaround you can remove the custom domain, let your app deploy, then re-add the custom domain and it should start working almost instantly.

The actual problem was with the SSL certificate. Anyway, thank you Charith for your support. – Chamupathi Gigara Hettige Dec 25 '20 at 10:52
