Multidomain certificate is not valid for a subdomain

[desytec]

Hello,

I have purchased a multi domain certificate. I have added a new website and assigned that certificate. That website is for a subdomain, but when I load the site, it sends an error telling that the connection is not private.

When I used https://comodosslstore.com/ssltools/ssl-checker.php tool for that subdomain, this is the error:

"The domain name does not match the certificate common name or SAN!"

By seeing the SANs, these are:

"Alternative names (SANs) : www.domain1.cl, www.domain2.cl"

FQDN for the subdomain is: f4.domain2.cl

How can I solve it?

Thanks
Jaime
