Answer 1

You should set root based on the location you are setting, because the location will not be appended to that, so you should fix this block:

location /phpmyadmin {
    index index.php index.htm;
    root /usr/share/phpmyadmin;
}

Please confirm if you have single domain certificate, a wildcard certificate or multi domain certificate.

If you are using a single domain certificate (say abc.com) it will not work for xyz.abc.com or 123.abc.com. It will work for only abc.com

If you have procured a wildcard certificate , please check and confirm if the subdomain is a first level sub domain or second level sub domain. wildcard certificates secures only first level sub domain. So *.abc.com certificate will work for 123.abc.com, xyz.abc.com . But it will not work for 123.xyz.abc.com.

If you have procured a multi domain certificate, then check if the sub domain URL is added as SAN to the certificate.
