No matching security types

I’m trying to connect to a Vine Server (2.0) and I’m getting the error:
No matching security types

This is from RealVNC Viewer 4.1.2. I get similar errors from TightVNC’s viewer.

Strangely enough, one of my hosts running Vine Server works fine. All the others are set up exactly the same and don’t work.
Port 5900 is open, I just can’t connect. I don’t even get prompted for a password.
Anyone know what might be going wrong?

This is almost certainly because you are running Apple Remote Desktop (which takes over port 5900). You can either disable ARD in System Preferences -> Sharing. Or you can run Vine Server on another port, like 5901.
