Amazon EC2 UDP connect failed
There has been a lot of power outages, and I know that amazon's cloud services have been severely affected.. http://hardware.slashdot.org/story/12/06/30/162250/more-uptime-problems-for-amazon-cloud
You have opened a socket using UDP. Telnet is a TCP-based utility. Basically, you're calling a phone number in China and asking why they aren't speaking French ;-)
please test if you have UDP ports opened in your 'security group'
Yep, UDP port open.
To test sockets in general, and UDP sockets specifically, use the "netcat" program.
This works:
nc -u
ec2-50-19-202-144.compute-1.amazonaws.com
9930But my game still doesn't... mmm.
Even this sample program doesn't work

test.exe -p UDP -n ec2-50-19-202-144.compute-1.amazonaws.com -e 9930

test.exe -p UDP -n ec2-50-19-202-144.compute-1.amazonaws.com -e 9930

What does wireshark say on the machine you run "nc.exe" on?
Are you sure the Amazon provisioning is set up to allow UDP in on the public IP? If it works with netcat on the server, but not with netcat on your client, then that's the most likely problem.
Could also be local firewalls on the client, on your router, or on the server itself.
