Firebase hosting using custom domain has SSL cert pointing to firebase.com

Question

I am able to complete the connect to custom domain step successfully and https://example.com is correctly loading my static file app which is hosted on Firebase.

However, browser is warning about the site's SSL certificate is not matching example.com. I looked at the certificate and it is of firebase.com, not mydomain.com.

This certificate is provided by Firebase for example.com (my custom domain name) and I expect it to be matching it. Is this expected?

I know the other solution is to get my own certificate for example.com. However, it seems that Firebase won't let me deploy my own cert.

Update

I retried it some time back and it is fixed. And the whole suite of firebase db/functions and corresponding sdk/cli are working really well. Great for small dev team.

Solution

Solution: Don't have to do anything about it other than just wait.

Faced the same problem when connecting to my custom domain on Firebase Hosting. However, it will only be insecure when the status is pending. The status can be found on your Firebase Hosting Dashboard.

My connection turned secured with a green lock after around 3 hours, and the status reflected in the dashboard changed to connected.
