Works fine in development and when deploying to Galaxy. However, when deploying with Meteor Up, I get continual 502 errors in the client console when submitting the form. I tried deploying it again without an SSL proxy and got continual connection errors.
This problem only occurs when attempting to send email. I have the MAIL_URL environment variable set correctly and all ports are open.
The client error shows net::ERR_CONNECTION_REFUSED in the console and the Network->XHR shows GET requests failing for http://app.com/sockjs/info?cb=[some random string].
