Problem with component Google Assistant

Good morning,
I have problems with the component of Google Assistant, when I try to activate the project created with the google console in the app of google assistant on the smartphone tells me that there is no connection, someone knows how to solve?

As explained in the component docs, you’ve set up port forwarding, with an SSL certificate for your domain, etc?

yes, I have done everything, opened the created ports, a domain and created ssl certificates for https

And tested it?

yes, I’ve tested them and they work
