Google Assistant installation wont work

After so much trying, and asking on the Discord group, and the help from @Tinkerer & @cogneato im lost in every thing, Google Assistant just doesn’t work for me.

I’ve tried everyting what is possible followed every step in the tutorial several times. Resetting my Google Home, deleting my project and starting over. Just nothing is working.

Account linking in Actions on Google
Client information client id copied from my configuration.yaml
Authorization URL: https://XXXXX.duckdns.org/api/google_assistant/auth

My portforwarding is 443 -> 8123 (ports are open can connect to my Pi3 with dns (page is secure SSL)

When i want to add [test] my test app to link in google home, its only cying for “Couldn’t update setting, check ur connection” Restarting my phone, restarting router everything is rebooted. nothing is helping.

Im now completely lost, and im tempted to trow it out the window, working already 60+ hours to get it working, so u know how much i did already to get it working.

Configuration.yaml

My google home is working…

But I do not have the below in my config.

I also have https://XXXX.duckdns.org:443/api/

I have the same as @Don_Lim . Add the port number to the url.

i’ve tried to add the port number in the gactions, but that ain’t helping me, what i can see if i try to make a new project it is going to the old url of an other project. How can i fix this? i’ve tried to delete all projects resetting google home, and it still goes to an old url / old duckdns link what doesnt exist.

Don’t post your api or auth tokens here.

Api token is hidden with some XXXXXX

Oke, so first of all Happy new year viewers.

I’ve been testing on an other gmail account with a new project, and added my port 443 in gactions. It seems that its still not working. When i open the google home app, the test app is visible, and when i click the app it is only saying Couldn’t update the setting, check ur connection what to do now?

Do it twice… My setup usually works the second time adding it to the assistant. Not sure why. And it always crashes when i try to add rooms to the devices, so I just leave without adding then do it after the devices are added.
