Resend nodemailer - not sending emails

It was working before, but I'm getting this error in development and production recently

There is an error with the email configuration you have provided. Error: Connection timeout

Failed to send mail to email@gmail.com, subject: Reset Your Password
    err: {
      "type": "Error",
      "message": "Connection timeout",
      "stack":
          Error: Connection timeout

      "code": "ETIMEDOUT",
      "command": "CONN"
    }

// server.ts
import nodemailer from "nodemailer";
// resend
const transport = nodemailer.createTransport({
    host: "smtp.resend.com",
    secure: true,
    port: 465,
    auth: {
        user: "resend",
        pass: "re_password",
    },
});

...
await payload.init({
        secret: process.env.PAYLOAD_SECRET,
        express: app,
        email: {
            fromName: "Eustachio",
            fromAddress: "support@website.com",
            transport,
        },
        onInit: () => {
            payload.logger.info(`Payload Admin URL: ${payload.getAdminURL()}`);
        },
...

I have checked firewalls for port 465 and it is open, I don't if there is another port or ip that is trying to communicate with the server and it isn't open

Any help would be great, please. Thank you
