Configuration/Authentication Issue 7.0.1
Installed the most recent version 7.0.1 of the homebridge-nest-cam plugin and unable to get the plugin to generate the token. I have gone to settings and entered my username and password for my Google Account. I have authorized the login request through the Gmail app. Immediately get:

Could not get code. Error: Error: Request failed with status code 400
Could not generate refresh token.

I have cleared the Homebridge Accessory Cache
Removed the Nest Cam Plugin and configurations.

Attempted manual configuration per instructions. No change.
