I've been getting this error when i try to send emails.

So i did a set up on digital ocean droplet, installed nginx and every other thing i need.

API works fine, but when it gets to sending emails it fails

This is my logic for sending email

`import 'dotenv/config';
import { sendGridConfig } from '../config/config';
import sgMail from '@sendgrid/mail';

sgMail.setApiKey(sendGridConfig.apiKey);

export const sendMail = async (
to: string,
name: string,
data: any,
templateId: string
) => {
try {
await sgMail.send({
to,
from: sendGridConfig.sender,
templateId,
dynamic_template_data: data,
});
console.log("Email Sent Successfully");
} catch (err) {
console.error("SendGrid Error:", err.response?.body || err.message);
throw new Error("Email Failed to Send");
}
};`

Sendrid mail version => 7.7.0
downgraded from 8.8.0 both version fails

Nodejs version => v20.16.0
Nginx version => nginx/1.26.0 (Ubuntu)
Yarn version => 1.22.22
