Hello Railway Support,

I am experiencing a 'Connection timeout' error when trying to connect to smtp.gmail.com:465 using nodemailer in my Node.js application. The error occurs consistently on Railway, while it works fine locally. The logs show:

- Error: Connection timeout at /app/node_modules/nodemailer/lib/smtp-connection/index.js:899

- ETIMEDOUT

I have tried:

- Increasing connectionTimeout and greetingTimeout

- Using port 465 with secure: true

- Verifying environment variables

Could you please check if there are network restrictions or firewall rules blocking outbound connections to smtp.gmail.com on ports 465 or 587? Any assistance would be appreciated.

Thank you,
