Google Home Integration failing to link

Tags: #<Tag:0x00007f73a55e1008>

Hello folks, anyone else having issues to link the [test] my test app to the Google Home account?
Google home redirects to my HA duckdns ulr, I successfully log in and the account does not link. I had a similar issue with other accounts as well.
I searched the internet for similar issues, seems like there are more account integrations having the same problem.
Anyone else is facing the same issue?
