The first thing you should do is set your apps to "Unlisted" rather than "Private".
The second thing is: you should contact Cameyo support so that they open your server for unauthenticated users. Please indicate your server's name.
I also run a server and need this done. The only link to support was at http://www.cameyo.com/contact but it says above the form that to use the forums for technical support requests, which I believe this falls under. How do I contact support?
