The most common errors during domain connection:
1. If the error "page not found" appears when you open your domain/subdomain, it means that your DNS records are not updated yet.
You have to have the same record for the lower level www subdomain. For example, is the subdomain you use is quiz.website.com, then you have to have the second record for www.quiz.website.com.
2. If the error "404 this quiz does not exists" appears when opening your domain/subdomain

It means that you have inserted the wrong domain / subdomain in the quiz.

CORRECT:
3. If you get the error "connection is not secure", it means that the SSL certificate has not yet been issued. Please make sure you have only one A record per domain/subdomain and check it has the right address and no AAAA records. If there is a second record A or AAAA, then they need to be deleted. After that, SSL certificate will be issued within an hour.
If all this does not help, please contact the customer support service of your registrar, that is, the service where you bought the domain.
