Odd WebSockets Issue

Hi, all-

I'm using WebSocketSharp for a project I'm working on and I'm having a strange issue. I have a functional node.js server running the backend, but it only works on the local machine. When I try to push it to my remote host, Unity can no longer connect to it. I thought I may have set up my remote machine incorrectly (unopened port, etc.), but I have another app (written in OpenFrameworks) on the same machine that's running unity that connects just fine. The end goal is an iOS app, but I've been testing it on my Mac.

Any ideas what might be going on? Any advice would be useful.

Thanks!
