java.io.FileNotFoundException: http://192.168.0.160:8800/xbmcCmds/xbmcHttp?command=SendKey(270) about boxeeremote HOT 3 OPEN

You had mentioned that you forwarded your ports. Is your phone on a different 
network 
from your Boxee machine? 
Are you using WiFi or 3G?
Also, have you tried using the automatic host discovery? Are the results any 
different 
then?

Thanks for reporting this.

I have the exactly same problem!

Unless that the sendkey is (271)

I have the same problem.

Using Boxee.
Using Wi-Fi.
Using default port, empty password.
Phone is on the same network as the computer with Boxee.
SendKey code varies, depending on the action that i try to perform on boxee 
remote (of cause).
Automatic host discovery doesn't help.
Rebooting computer doesn't help.
Rebooting smartphone helps in most cases temporary.
