Email Configuration Error

Hello everyone, I am having problems with the email configuration in OJS3.3.0-17. Can you tell me what I missed?

[email]

; Use SMTP for sending mail instead of mail()
smtp = On

; SMTP server settings
smtp_server = smtp.gmail.com
smtp_port = 465

; Enable SMTP authentication
; Supported smtp_auth: ssl, tls (see PHPMailer SMTPSecure)
smtp_auth = ssl
smtp_username = js.info@***.edu.ph
smtp_password = ****************
;
; Supported smtp_authtype: RAM-MD5, LOGIN, PLAIN, XOAUTH2 (see PHPMailer AuthType)
; (Leave blank to try them in that order)
; smtp_authtype =

; The following are required for smtp_authtype = XOAUTH2 (e.g. GMail OAuth)
; (See https://github.com/PHPMailer/PHPMailer/wiki/Using-Gmail-with-XOAUTH2)
; smtp_oauth_provider = Google
; smtp_oauth_email =
; smtp_oauth_clientid =
; smtp_oauth_clientsecret =
; smtp_oauth_refreshtoken =

; Enable suppressing verification of SMTP certificate in PHPMailer
; Note: this is not recommended per PHPMailer documentation
; smtp_suppress_cert_check = On

; Allow envelope sender to be specified
; (may not be possible with some server configurations)
; allow_envelope_sender = Off

; Default envelope sender to use if none is specified elsewhere
; default_envelope_sender = my_address@my_host.com

; Force the default envelope sender (if present)
; This is useful if setting up a site-wide no-reply address
; The reply-to field will be set with the reply-to or from address.
; force_default_envelope_sender = Off

; Force a DMARC compliant from header (RFC5322.From)
; If any of your users have email addresses in domains not under your control
; you may need to set this to be compliant with DMARC policies published by
; those 3rd party domains.
; Setting this will move the users address into the reply-to field and the
; from field wil be rewritten with the default_envelope_sender.
; To use this you must set force_default_enveloper_sender = On and
; default_envelope_sender must be set to a valid address in a domain you own.
; force_dmarc_compliant_from = Off

; The display name to use with a DMARC compliant from header
; By default the DMARC compliant from will have an empty name but this can
; be changed by adding a text here.
; You can use '%n' to insert the users name from the original from header
; and '%s' to insert the localized sitename.
; dmarc_compliant_from_displayname = '%n via %s'

; Amount of time required between attempts to send non-editorial emails
; in seconds. This can be used to help prevent email relaying via OJS.
time_between_emails = 3600

; Maximum number of recipients that can be included in a single email
; (either as To:, Cc:, or Bcc: addresses) for a non-privileged user
max_recipients = 10

; If enabled, email addresses must be validated before login is possible.
require_validation = Off

; Maximum number of days before an unvalidated account expires and is deleted
validation_timeout = 14

And this is the error I get if I try sending emails in the User & Roles.

SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

I have tried using SMTP tool to check my connection and it’s fine and working. I have recently used OJS3.4.0-4 for this but even though with right configurations and everything I still can’t get the emails to work thru google emails. However when I tried using emails created from the main server, everything works perfectly but it takes prolly like 5 minutes before the emails are sent. But using server emails for this isn’t recommended by our supervisor. I would appreciate your help!
