Why Wait
I have created a subdomain shop.tonggarden.com.sg it’s work fine with cloudflare setup however if i try to access www.shop.tonggarden.com.sg it will give me ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Test Before You Post
It work fine if i disable the cloudflare proxy. It’s already a week ok more so DNS and SSL certificate should be properly propagated
I’m not sure what you mean, a two level deep subdomain is not ‘standard’ and will require additional hostnames on the certificate. You can do this with either the ACM add-on or with a Business Plan and custom certificate.
Alternatively, you can bypass Cloudflare on that subdomain, by unproxying it, and handle the certificate on your server, if you want.
