Amazon web services – Access AWS SES from a lambda function that is inside a VPC

I have already set up the necessary VPC endpoints as stated here.

However, when inside of my Lambda function (using Node.js) I do:

const sesClient = new SESClient({ });
...
await sesClient.send(sendEmailCommand);

it times out after 5 minutes.

Should a specific endpoint be specified when initializing the SES Client?

    As Allan Chua suggested, using the SES SMTP interface with a tool like nodemailer works.

    nodemailer.createTransport({
  port: 587,
  host: `email-smtp.${region}.amazonaws.com`,
  auth: {
    user: smtpUsername,
    pass: smtpPassword
  }
});

    Please check the corresponding SES API logs from CloudTrail to make sure that the SES API calls are going through your VPC endpoint properly. I have a strong hunch that the SDK is connecting to the API and VPC endpoints for SES are meant for SMTP. To solve your problem, please use SMTP interface or introduce a NAT Gateway to your VPC if your use-case allows it.
