Vuze gives an error that "0 users" are connected, and a firewall error. I don't think it's the network, because the same network was working fine just a few hours ago.

Vuze was working perfectly up to earlier today. I had been running 12.04 LTS, but did a clean install and put on 13.10 desktop. Now, vuze just doesn't connect.

The specific diagnostic error:

Testing port 24488 ... NAT Error - Connect attempt to (your computer) timed out after 20 seconds. This means your port is probably closed.

Although, just a litte while ago that worked fine, even after the clean install, but was still giving "0 users" -- so I don't put much into that diagnostic.

While it's a wireless connection to a router, it was working fine earlier today. I highly, highly, doubt the router is the problem. I do not have physical access to the router.

Switching the port to 24489 gives:

Testing port 24489 ... OK !

but still "0 users", so that's no progress at all.

What does "0 users" really mean, and how do I get connected again? Proceeding on the assumption that the network isn't the problem (it was working earlier today fine), that the break is correlated exactly with the clean install, and that I don't have physical access to the router.

What diagnostics can I run on Vuze itself?

Here is the startup from console:
