You cannot change the domain that is set as your primary domain. This feature is activated once you unmark this domain as primary domain.
If you want to change a domain purchased from a third-party website, you will need to disconnect it from your Cafe24 store, then reconnect it with the [Connect existing domain] feature.
SSL certificateSSL certificate range
Cafe24 offers an SSL certificate for important pages that deal with personal information, such as the login page, account creation page, and checkout page.
SSL certificates cannot be issued for Cafe24's default domain. You can only request an SSL certificate for the domains you have added and connected yourself.
e.g., skin.STORE_ID.cafe24.com, m.STORE_ID.cafe24.com, etc.
Make sure you also request another SSL certificate for any new domains you add.
If you are using the SSL certificate feature, you will need to edit external scripts and links that redirect to HTTP by inserting it in your theme file yourself.
SSL request status
Installation complete: Your SSL certificate has successfully been installed.
Issuance error: An error has occurred while installing the certificate. Complete the installation by clicking the [Request certificate] button.
Awaiting issuance: Certificate issuance is in progress.
Not installed: SSL certificate has not been installed.
Some domains may be rejected due to certificate policies. If your domain has been rejected, it will be marked as "Issuance error".
e.g., Domains that contain "bank", certain certificate issuance agencies (comodo, verisign, etc.), famous companies or similar domains, or cloud provider domains (aws, google, etc.) could be market as "Issuance error".
If your domain's name server isn't Cafe24, you will not be able to receive a certificate.
Make a new request 2 days later if you change it to the Cafe24 name server.
If you are using an external script because you changed your theme, check whether this externa script's URL supports HTTPS.
Check with the script provider whether their feature is supported.
