I can't get Gmail SMTP to connect and I'm getting this debug info on tls:
2017-12-05 16:40:25 SERVER -> CLIENT: 220 smtp.gmail.com ESMTP q9sm1085224pfl.116 - gsmtp

SMTP Error: Could not connect to SMTP host.
Message could not be sent.Mailer Error: SMTP Error: Could not connect to SMTP host.
I have tried SSL too, which says "can't connect". I have never had an experience like this.
Note: I am using PHPMailer
Does anyone have the same issues or is it just me ?
