Is it possible to get an alias domain into the origin certificate of cloudflare?

Hello everyone,
I have a domain.com and an alias.com (which is an alias for this domain). domain.com is registered with cloudflare and I’m using the free origin certificate to secure the domain url. However the alias.com isn’t included in this certificate so it’s not working with https.

Is there any way to solve this issue? Can I include the alias domain somehow to cloudflare?

Best regards,
Michael.

Are you saying you do not have a certificate on your server?

You can create an Origin certificate that covers both domains, from the documentation:

You can include up to 100 hostnames or wildcard hostnames on a single certificate and can include hostnames for other domains within the same Cloudflare account.
