Hi,
Since trying out 3.0b3, I've been unable to connect to my iPod Touch over SFTP. I keep on getting an "I/O Error: Connection Failed" message with the cryptic explanation that "there was a problem trying to connect to 10.0.1.x". I have confirmed that my username and password are correct, and I haven't changed any connection settings that might have caused a conflict. Also, I have verified that this appears to be an issue isolated to the beta because downgrading to the latest stable release (2.8.5) immediately resolved the problem. I was able to connect just fine. However, on 3.0b3, Cyberduck either hangs while attempting to establish an SFTP connection, after which I'm forced to close the connection, or else it simply refuses to even try and a) immediately gives the error message or b) doesn't even start after a previous failed attempt.
AFAIK, this appears to be a bug of some sort, unless I'm doing something obviously wrong. Aside from this, everything else has been working fine so far. Thanks for the great work!
