Error with registration mail

aberral commented 1 month ago

Hi, I've been trying to run Kettlewright on my server as a Docker container. The container is running, the website is accessible, but when I try to register an account the container throws this exception (as seen in the logs):

NFO:root:Not using Redis; falling back to local eventlet sessions. Consolidation complete. Data written to app/static/json/backgrounds/background_data.json Consolidation complete.

I've tried to pinpoint where the error is coming from, but have been unable to do so. The .env configuration that I have is something like this:

BASE_URL=http://127.0.0.1:8008
SECRET_KEY=***********
SQLALCHEMY_DATABASE_URI=sqlite:///db.sqlite

# Gmail config
MAIL_SERVER=smtp.gmail.com  
MAIL_PORT=587              
MAIL_USE_TLS=1              
MAIL_USERNAME=****@gmail.com  
MAIL_PASSWORD=*********

# Optional
REQUIRE_SIGNUP_CODE=False   
# SIGNUP_CODE=[your_signup_code]  

# Redis
USE_REDIS=False              
# REDIS_URL=redis://redis-server:6379/0

I've tried to exec into the container and pinging 'smtp.google', which is successful. I've also run the following Python script to test that the credentials that I have for gmail are working as intended:

from flask import Flask
from flask_mail import Mail, Message

app = Flask(__name__)

# Mail config
app.config['MAIL_SERVER'] = 'smtp.gmail.com'
app.config['MAIL_PORT'] = 587
app.config['MAIL_USE_TLS'] = 1
app.config['MAIL_USERNAME'] = 'sender@gmail.com'
app.config['MAIL_PASSWORD'] = '****' 
app.config['MAIL_DEFAULT_SENDER'] = 'sender@gmail.com'

mail = Mail(app)

with app.app_context():
    msg = Message("Test mail",
                  recipients=["recipient@gmail.com"])
    msg.body = "Test mail sent from Docker"
    try:
        mail.send(msg)
        print("Success!")
    except Exception as e:
        print(f"error")

This test email works and is received (both sent and received by gmail accounts). So I am at a bit of a loss as to how to try to fix this problem. I have also ruled out a port or system related error as I have tested it on another machine with and without other containers occupying port 8000. I hope you can help me solve this problem and congratulations on the app, it is fantastic.
