Nessus does not send e-mail after setting up smtp server

I have entered the following settings in the Nessus SMTP area:

Host: smtp.gmail.com
Port: 587
Encryption: Force TLS
Auth Method: Login
username: someuser@gmail.com
password: mypass

I get the following error once I try send a test e-mail:

Error (500): It was not possible to email this scan: SMTP Authentication method 'LOGIN' failed: 534-5.7.14 Please log in via your web browser and 534-5.7.14 then try again.
