[Errno 111] Connection refused - gmail smtp - paid account

Hi. I have a paid account, but I appear to be having trouble sending email via gmail's SMTP server. I'm using an app-specific password for gmail. The relevant code from my app:

from flask import Flask, render_template
from flaskext.mysql import MySQL
from flask import request
from flask_mail import Mail, Message

app = Flask(__name__)

mail = Mail(app)

app.config.update(
                    DEBUG=True,
                    MAIL_SERVER='smtp.gmail.com',
                    MAIL_PORT=465,
                    MAIL_USE_SSL=True,
                    MAIL_USERNAME = 'XXXX@gmail.com',
                    MAIL_PASSWORD = 'XXXXXXXXXXXXXXXX'
                    )

@app.route('/curated_entries/', methods = ['GET', 'POST'])
def curate_tweets():
   # other code that works omitted, pulling data from an html form
    msg = mail.send_message(
        'Hello',
        sender = 'XXXX@gmail.com',
        recipients = ['XXXX@XXXX.com'],
        body = "This is the email body")
    mail.send(msg)
    return render_template('confirmation.html', data=curated_entries)

Here is the error log. Any thoughts on what I'm doing wrong? Thanks.

And here's the WSGI file, which I don't recall altering:

import sys

# add your project directory to the sys.path
project_home = u'/home/AccountName/mysite'
if project_home not in sys.path:
    sys.path = [project_home] + sys.path

# import flask app but need to call it "application" for WSGI to work
from curate_newsletter import app as application

One thing to check- can you run similar code from the console and get it working? If that doesn't work, can you run code locally and get that working?

Thanks, Conrad. The solution ended up being to move the line "mail = Mail(app)" to after "app.config" – it was initiating before the user credentials had been specified:

app.config.update(
                    DEBUG=True,
                    MAIL_SERVER='smtp.gmail.com',
                    MAIL_PORT=465,
                    MAIL_USE_SSL=True,
                    MAIL_USERNAME = 'XXXX@gmail.com',
                    MAIL_PASSWORD = 'XXXXXXXXXXXXXXXX'
                    )

mail = Mail(app)
