HelpProxy Server - Orape

I'm trying to play on the Proxy Server so I can mess around with some stuff, but I can't get it to work.
I've gone to Global Settings and set my client as trusted, but I'm still getting the Socket-Server IO Error.
I've looked all over for some sort of setup guide, but everything seems to be outdated (ie. the stickied thread in this forum).
Thanks!

edit: Is the Proxy Server the same as Realm Relay? If not, how do I use Realm Relay?

Realmrelay is easy to use. Just download it from Here.

Make sure you have the latest packets.xml file. Code is Here.

Then start it up and choose your server (Update Server List !)

Select proxy server on game and click 'START' on Realmrelay. Shoud work. Make sure you don't close out of Realmrelay, Leave it open.

Same here. I don't use proxy server via realm relay only use it for Realmbot. Which is better for actually being on it not all the other scripts.
