How to get smtp to work in production droplet

Hi all, I’m trying to set up an email form that uses Google’s smtp servers and ActionMailer that sends emails on form submission. I should start out by saying that this works fine in development on my local machine and in production on Heroku, but not from my digital ocean droplet.

Basically, when I submit the form, it sits for 30 seconds and returns an internal server error. I suspect the problem is in ActionMailer because if I remove the ActionMailer code from my controller, the form submits as expected (but obviously sends no email).



  resources :home_page, only: :index
  match '/email' => 'home_page#send_email_form', as: :email_form, via: :post
  root :to => 'home_page#index'


def send_email_form
        @message =[:message])

        if @message.valid?
        respond_to do |format|
            format.html{redirect_to root_path}

          respond_to do |format|
            format.html{redirect_to root_path}


<%= form_for @message, url: email_form_path, remote:true do |f| %>

    <%= f.label :name, class: 'label' %>
    <%= f.text_field :name, class: 'input', placeholder: "Enter your name" %>  
    <%= f.label :email, class: 'label' %>
    <%= f.text_field :email, class: 'input', placeholder: "Enter your email" %>
    <%= f.label :phone, class: 'label' %>  
    <%= f.text_field :phone, class: 'input', placeholder: "Enter your phone number"%>
    <%= f.label :message, class: 'label' %>
    <%= f.text_area :body, class: 'input', placeholder: "Enter a brief message"%>
    <%=f.submit 'Send Message', id:'submit', class: "margin-top-20 alt-button button radius large"  %>

<% end %>



            $('#submit').prop('disabled', 'disabled');
            var target = document.getElementById('spinner');
            var opts = {
                lines: 13, // The number of lines to draw
                length: 10, // The length of each line
                width: 10, // The line thickness
                radius: 20, // The radius of the inner circle
                corners: 1, // Corner roundness (0..1)
                rotate: 0, // The rotation offset
                direction: 1, // 1: clockwise, -1: counterclockwise
                color: '#000', // #rgb or #rrggbb or array of colors
                speed: 1, // Rounds per second
                trail: 60, // Afterglow percentage
                shadow: false, // Whether to render a shadow
                hwaccel: false, // Whether to use hardware acceleration
                className: 'spinner', // The CSS class to assign to the spinner
                zIndex: 2e9, // The z-index (defaults to 2000000000)
                top: '50%', // Top position relative to parent
                left: '50%' // Left position relative to5 parent
            var spinner = new Spinner(opts).spin(target);



    var form=$('#new_message');  
    var form_header=$('.form-header');
    <% if @message.valid? %>
        form.append('<%= j render(:partial=>"confirmation")%>');

Is there anything special I need to set up in unicorn or in nginx to make the AJAX request work? Also FWIW, if I remove the remote:true from my form_for tag, it doesn’t redirect either which leads to believe that the problem is in the ActionMailer somewhere.

Anyone have any ideas? Thanks so much!

Things look ok here. Have you checked any logs to see for any errors? Such as the web server logs, likely in /var/log/nginx/error.log

Also, you should reach out to support by opening a ticket as mail ports can be blocked on some accounts and they can help you get that removed. It is possible this is also part of the cause since it seems to stall. This suggests a timeout, which could be the system trying to connect.
