problem with certificate on the subdomain

[techcomputerworld]

the problem is that I have the subdomain registered in Web Server Setting, SSL certificates, there I have the certificate of a subdomain and it keeps giving me the warning that the certificate is wrong when I enter the web page.
In addition to having registered it and there I really want to make an index.html page to redirect everything to my main domain because it keeps taking me to the page www.domain.com, what solution does it have?

Hi, try to restart varnish (if in use) and/or reinstall the SSL.
