Hi,
Error 400: redirect_uri_mismatch
The redirect URI in the request, http://www.odootest.com:8069/auth_oauth/signin, does not match the ones authorized for the OAuth client. To update the authorized redirect URIs, visit: https://console.developers.google.com/apis/credentials/oauthclient/xxxxxx/xxxxx........
Thanks!
I have having the same error and issue in all attempts to sync google. The Calendar, Email, Replies, etc pop with the same error, also in the App as well.
