I had this yesterday with a customer, you might need to enable API access.

Watch your log, while you connect your Google Mail:

tail -f /opt/zammad/log/production.log | grep ERROR -A10

and try to connect again. Does it show more information in the error?

We really need to update the documentation, the dialogs changed too much.
