Hi,
I´ve done all steps in this tutorial:
Google Assistant integration
My instance is accessible from the Internet (IPv4 and IPv6) with an SSL certificate.
When I integrate my [test] into the Home app, I can log in to my Home Assistant, but shortly afterwards I get a “connection error”.
I’m stuck and need help.

When I push Synchronize on Home Assistant:
