[Android Software Development] Monsterkater:
I can't get a connection with the proxy activated (at home without proxy it works fine), too, I added a few logs. If I don't activate the rule for localhost direct connect, the Android Tool can't open a connection to the android (it counts to 25 and then just stops). If I activate it, it seems to work in Android Tool, but my HTC One X still has no internet connection and Proxifier doesn't seem to connect properly.

Log from AndroidTool with Proxifier rule for localhost direct connect NOT activated:

Because the proxy check didn't work as HTTPS, I set the proxy as HTTP. But in the browser on this PC HTTPS is no problem whatsoever, facebook and everything works like a charm with HTTPS. So I set the proxy as HTTPS regardless of the failed test, now I get this error messages:

[06.25 11:03:14] AndroidTool.exe - 184.173.179.41:5222 error : Could not connect through proxy xxxxx:8080 - During authentication negotiations proxy returned unexpected status code 403

I just don't know where to continue my hunt for mistakes, please help if you can.
