XT-GUI on headless/GUIless system?

[Hoho]

I'm running a linux VPS with no GUI, and would like to be able to use the new XT-GUI from a browser on my local machine.

With Grunge's help , I set up a nginx as reverse proxy, and can access the XT-GUI from my local machine, but it fails at password creation.

Any other ideas? Anyone else having luck?

So, I've now made sure port 5000 is open, and shut down the nginx reverse proxy...

I can browse to 123.456.78.90:5000 and get to the log in screen, but still when I type a password and click the button... nothing happens.
