Adguard detects website as false positive if the common name is not wildcard, how to resolve this issue?

[oslon]

Assume a website whose Common Name of SSL certificate is this

myonlinebank.example.com

Assume a website whose Common Name of SSL certificate is this

*.example.com

Users are using adguard dns.

dns.adguard.com

And when they try to access the first site(the one without wildcard certificate), they get this error:

NET::ERR_CERT_COMMON_NAME_INVALID

Why? And what are the potential clever solutions(by using nginx config or otherwise) of this issue except purchasing a new wildcard certificate?

I’ll put everything that I know about SSL protocol here:

We’re using nginx server with we’ve enabled TLS.

And when they try to access the first site(the one without wildcard certificate), they get this error:

NET::ERR_CERT_COMMON_NAME_INVALID

Why?

Because the domain they are accessing is difference from the one in the certificate. For example, they are accessing www.example.com but the certificate says myonlinebank.example.com. The wildcard certificate will allow this because the subdomain can be anything. The non-wildcard certificate requires the names to match exactly.
