Question domain alias and wildcard ssl certificate

Hi,

i have a domain: example.tld and a subdomain test.example.tld
I have setup a domain alias example2.tld for example.tld. without 301 redirect.

If i open example2.tld in the browser it shows me the same webpage as example.tld. Thats great!

I have installed the free lets encrypt certificate for example.tld and also checked the domain alias example2.tld. I have selected a wildcard certificate to ensure subdomain.example.tld works the same way.

The certificate was installed successfully. But:

- If i open https://example.tld -> OK
- If i open https://example2.tld -> OK
- If i open https://subdomain.example.tld -> OK
- If i open https://subdomain.example2.tld -> NO CERTIFIATE FOUND

It looks like the certificate is only installed for the primary domain alias but not for a wildcard like subdomain.example2.tld

How i can i get a correct certificate?
