Point subdomain to firebase hosting

[celinafregoso99]

I have Godaddy hosting. My requirement is simple,

I need to point app.example.com to example.web.app

For that I have done these steps

I verified the main domain with the txt entry.
I also did a txt entry for that sub domain
I created A records with the IP's provided by firebase where host is app.example.com
Godaddy team said we need to create a CNAME, so we also created a CNAME entry where Name is app and value is example.web.app

Do i need to do anything else ? Shall I keep this CNAME entry or delete it ?

Its opening my link now but saying **This page is not secure (broken HTTPS).** , cretificate missing , issued to firebaseapp.com

What else do I need to do to make it work with https?

Hey there! It sounds like you've done the correct changes in DNS, as the site is opening properly and directed to the correct content. The https issue is something you would need to speak with firebase directly about, as it sounds like they issue a general SSL to their clients that may need to be replaced, but that issue is not because you did something wrong with the DNS.

I don't believe you'd need a CNAME in this case - just the A record for the subdomain is enough to get that pointed to the correct location.
