Smappee integration : OAuth authorization error while obtaining access token

[braham2019]

The problem

Tried to active the Smappee integration in HA:

1. entered client_id, client_secret in configuration.yaml & rebooted
2. got the prompt to login to the Smappee website
3. logged in using my app username and password. I login and it works fine, I can select my home
4. but when it returns to the HA screen, I get the error "OAuth authorization error while obtaining access token"

Log is showing
