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?

The error indicates that the redirect URL that you specified when creating the app via google's developer console does not match the redirect URL that vdirsyncer is using.

Vdirsyncer uses http://127.0.0.1 as a redirect URI. See this comment: #1028 (comment)
