500 (Internal Server Error) When I try to send an email in the Rails production environment

Status

In the inquiry function of the application deployed to AWS (EC2)
If you press the Send button on the confirmation screen,
A heading error occurs.
It works fine in the local environment.
I would like to know how to solve this problem.

The error screen displayed by Chrome shows the following:

Net::OpenTimeout in InquiryController #thanks

If you press the Send button from the confirmation screen of your inquiry,
The query controller's thanks method is called specification.
Your inquiry will be emailed to your administrator.

Because of the Timeout error, it is estimated that the port used by SMTP is not empty.What is the security group setting for EC2?--sugumura

As you pointed out, the outbound rules of the security group were set incorrectly.I added port number 587 and it was resolved.Thank you for your advice -- amaama
