Hey,

Does anyone know if AWS SES being blocked at at the network level is a known limitation of Railway?

See below for my debug trace.

Can you try moving your application to a different region?

Hello,

Outbound SMTP is only available on the Pro plan and above, while Free, Trial, and Hobby plans have SMTP disabled.

For sending emails from your application, please use a dedicated email service that provides HTTPS APIs. More information can be found in our documentation:

Best regards,

The Railway Team

Hi,

But i’m not using SMTP, it’s using the AWS SES API on HTTPS (port 443), see the trace.

Thanks

Railway does not block any HTTP requests. Does this same request work locally?

Yup, works locally with the same credentials. Also it’s a TCP timeout not a HTTP failure, so either Railway is blocking outbound HTTPS to SES API’s or AWS is blocking Railway.

Yup, so I moved it to US East and it works, must be something about the EU region...

I'm going to escalate this thread. To the team: is there anything that can be done with various service's blocking entire Railway regions? I've seen this more and more as of recently.
