Everything works as expected up to the point where I want to connect the service in my Google Home app. My Service “[test] …” appears in the search and when I click it the auth page of my HA instance shows in a browser window. After the login and some google progress icon turning it jumps back to the Google Home app but the service was not added.
Is it possible that the issue is cause by the DS-Lite characterisitc of my internet connection? I do not have a public ipv4 address. Maybe Google tries to contact my server through ipv4!?
Is there a way to configure the Google service to use ipv6?
