Resolving “NetGroup.Connect.Rejected” or when your Flash P2P apps stop working
November 2nd, 2010
I just ran into a problem with NetGroup.Connect.Rejected, my FMS4 server was running ok - I have even tried Cirrus/Stratus and I was still getting this error on demos, which were properly working before.
OK - so what is this error about?
It’s all about your Flash Player security and it’s basically telling you that you have denied access to some source. This happens, when you start developing apps on different PC and someone before you denied to use P2P or similar.
Solution:
1. Go to Global Settings
2. delete all or specific P2P settings in Global Settings
3. run your application again (it should be in browser, had sometimes problems with standalone apps, where dialog didn’t appear)
this dialog should appear. Click Allow and better Remember.
Don’t forget that these settings are inherited to all versions of Flash Player you have on your PC, even to betas or prereleases.
Good Luck!

Local Flash Peer-to-Peer Communication over LAN (without Cirrus/Stratus)
August 27th, 2010
Some of you guys were probably wondering how to establish P2P connections in the local network (LAN) without Adobe Cirrus. Yes. It’s possible. Using native IP-only multicast. Let’s build a simple chat with Posting. Adding Multicast broadcast is just a simple next step which I am sure you can accomplish by yourself with few hints from my article about Multicast
Open an IP Multicast connection. This can be done by specifying connection string as “rtmpf:”. Note, that this technique cannot be used for one-to-one communication. So no DIRECT_CONNECTIONS with NetStream, but you can do all RTMFP Group operations.
netConnection.connect("rtmfp:");
