Authorization ends with an error (400 Bad Request)

[jkolo]

Describe the bug

When I try to authorize, I go through all the steps (api.home-connect.com (email) => https://singlekey-id.com => api.home-connect.com (authorize) => https://my.home-assistant.io/redirect/oauth => Home Assistant) and on the last step I get a window saying Error. Home Connect integration with the same OAuth2 keys has no authorization problem.

Version of the custom_component

0.5.10

Configuration

home_connect_alt:
  client_id: !secret home_connect_alt_client_id
  client_secret: home_connect_alt_client_secret
  language: pl
