Ok, the first thing to is enable PHPMailer debug so we can find out what the actual issue is.

First of all, use this to debug the server:

$mail->SMTPDebug = 2;

Let us know what errors you see.

Ok, i’m assuming this is to do with the way Google’s security works. Somewhere in your settings there is an option that says ‘enable less secure apps’ (Use google to find where it is). Please enable this option and see if that helps.
