Troubleshooting

Email Not Sending

For Gmail users:

1. Enable 2-factor authentication
2. Create an App Password: https://myaccount.google.com/apppasswords
3. Use the App Password in your configuration

JWT Token Issues

# Check token expiration
from dwarapaal_auth.services import TokenService

token_service = TokenService()
payload = token_service.verify_token(token)
print(payload)

MongoDB Connection

# Check MongoDB is running
mongosh

# Test connection
from pymongo import MongoClient
client = MongoClient("mongodb://localhost:27017/")
print(client.server_info())
