I recently moved my Node.js app from shared hosting to a DigitalOcean Droplet. On shared hosting, sending emails via Nodemailer with SMTP worked perfectly. Since moving to the Droplet, emails are not going out at all. I am getting connection timeout errors on port 25 and port 465.
My code has not changed, the SMTP credentials are the same, and I double checked the firewall rules. Everything looks correct but emails just will not send.
Has anyone run into this after migrating to a Droplet? What is the fix?
