I was debugging an application tonight that uses Flex to connect an Android mobile application to ColdFusion via Flash Remoting. Every time I tried to call the remote method via the RemoteObject I got the message:
Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed
So I checked my LAN settings and then played around with my Mac firewall control panel. It was disabled so I was baffled. I then came across this post that hinted that it could be my usage of the CheckPoint VPN-1 SecureClient. Disabling and closing the client had no effect, so eventually I figured out I had to just disable the security policy (Tools > Disable security policy). I hope this helps someone out there from ruining an otherwise perfectly good evening of coding!
