How do I add SSL with Firebase Hosting?

I uploaded my angular 4 project to Firebase Hosting and it works well on Firebase's domain. However, when I connect it to my custom domain it should use SSL but as you can see on the image below, SSL is not active.

How do I set up SSL with Firebase Hosting?

Solution

Firebase Hosting will only serve traffic over SSL. However it may take a bit of time before your custom domain propagates. During this time, you'll see the "not secure" warning and may even see a different domain name when you click it.

If the problem persists and you're not able/willing to share the domain name here, reach out to Firebase support for personalized help in troubleshooting
