Can't connect to VPS Ubooquity instance

Hi all

I have been using Ubooquity for a while (on my QNAP NAS), but I am going travelling soon and the NAS will be turned off for this period. So I want to set it up using a cheap DigitalOcean droplet. My files are stored on Amazon Cloud Drive (they are already backed up there, so why not use them...).

So I have created the droplet running Ubuntu 14.04, installed Ubooquity successfully to /opt/ubooquity. And installed acd_cli and mounted my amazon drive.

Everything looks like it is working properly, however I just cant connect from my home computers. I presume its an issue with connecting to a remote machine (port forward / firewall). Ubooquity is definitely up and running, i have allowed connections in my firewall. I believe that all ports are open by default on a DO droplet.

ps aux | grep uboo gives

root 4374 41.2 13.0 2058784 65384 ? Sl 04:44 0:02 /usr/bin/java -jar /opt/ubooquity/Ubooquity.jar -webadmin -headless -port 2022

sudo netstat -plunt gives

...
.tcp6 0 0 :::2022 :::* LISTEN 4374/java

What am I missing here?

If I curl http://dropletip:2022/admin in putty I can see that the correct page to create a password is coming up, but I can't access it via a webpage.
