Hi there, Its been days and I am stuck. Whenever I try to send email, I get “502 Bad Gateway” error. Configuration:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

I am using Ubunto OS with Nginx and Gunicorn. I have opened ticket twice with this issue but no one is responding. Hope someone here responds.

Hi there @mahawaqar9875,

There are a few things that you need to consider:

  • If you are using a firewall on your Droplet like UFW, make sure to allow the outgoing TCP traffic for port 465

  • If you are using a Cloud Firewall, make sure to allow the outgoing TCP traffic for port 465 as well

  • Once you have opened port 465, test this is actually the case by running the following command from your Droplet:

  1. telnet 465
  • If you have port 465 open already try running telnet from your Droplet to your mail server:
  1. telnet 465
  • Make sure that your Droplet’s IP address is not blocked by the firewall on your mail server

Let me know how it goes! Regards, Bobby
