LabVIEW SMTP With mailgun

I'm trying to use LabVIEW's SMTP Email Palate To send an Email from my Vi to my Email. My Code Snippet looks like this:

Current Code With Error

From What I can tell Via The Mailgun settings:

I've tried the same settings with GMAIL.vi as well and I ran into the same timeout error. What can I do to fix this process?

You may want to look into the following help page, which describes the process for sending emails from a VI:

Hey, I've looked into the page and have tried sending a test email without any luck. (Still getting a timeout error)

Could there be something else getting in the way?

Could you use a tool like Wireshark to capture the network communications between your computer and the server?

I've downloaded Wireshark, but I've never used it before. I'm able to capture data over the time I'm running my vi, but I don't see anything that looks like its going to mailgun or port 587

It's a complicated tool with a lot of features, but also can be a little tough to get it to do what you want at first. At a minimum we'd expect to see your computer trying to connect to the mail server on the configured port, even if the server didn't accept the connection or reply.
