Facts

Answer 1

Before I begin, let me preface this that there are many possibly solutions and outcomes between your server and the google server, so these may or may not work for different people.

1) SMTP is not very secure, so Google may be rejecting your request. I had this problem 6 months ago and the solution was enabling insecure apps under 'myaccount.google.com'

2) If that doesn't work for you then you may consider switching protocols.

from

'host' => 'ssl://smtp.gmail.com',

to

'host' => 'tls://smtp.gmail.com:587';
