Site not secure although SSL is configured on my domain

Hi everyone, I have an app using a prefix on my domain in cloudflare. My domain’s SSL is already set up including all the prefixes since I used asterisk.

But some of my clients who installed the app is encountering an invalid certificate message in their Chrome browser. Any ideas on this?

Hi @RodneyZan,

If you domain is formulalookout[dot]com, I am not seeing any Wildcard DNS set on the DNS dashboard.
To issue a SSL certificate on a subdomain, the DNS entry needs to be proxied.

I see a mix of grey clouded entries and orange clouded entries.
But I am not seeing any wild cards [*].

Can you please check your DNS set up again.

Thank you.
