Can't sign in for google calendar (redirect_uri_mismatch)

[ManuGraiph]

Hi,

When i try to sync my google calendar for the first time, the auth url opens with the following message:

You can’t sign in because this app sent an invalid request. You can try again later, or contact the developer about this issue. [Learn more about this error](https://developers.google.com/identity/protocols/oauth2/web-server#authorization-errors-redirect-uri-mismatch)
If you are a developer of this app, see [error details](https://accounts.google.com/).
Error 400: redirect_uri_mismatch

Tried with different browsers, in case the one i use was trimming the url, but same result; any idea what could it be?
