I'm trying to create a Flarum forum on my VPS, and I'm trying to host all of my emails through the service Elastic Mail. I've added these settings before because I used discourse before, but I don't know how I'm doing this wrong. Below is a picture of both my elastic mail settings, and my email settings on the forum. Below that is also the stack trace I get from the debug screen when trying to create a new account.
