SSL certification on subdomain

Hi Luke,

Thanks for your help.
I am little bit confused about the things like the domain tslvirtualconference.com is from different domain provider but the DNS is managed by you and it’s absolutely working fine but as I am using different technology to work on backend so I have created a subdomain on that server i.e. api.tslvirtualconference.com and made a A record entry on your DNS panel pointing to that server IP address and that also works fine but SSL not applied to that and it’s because of reason you mentioned on previous message so in that case I made a CNAME entry that is pointing to your default sub domain i.e. https://hopeful-fermat-ce8055.netlify.app. If everything is setup correctly then in that case when I hit your sub domain it should point to my sub domain and it should open my sub domain website but that’s not happening, it is still pointing to primary domain.
I am really confused about the things.
Please guide me to correct path.

Thanks
