Is it possible that you had idb running before and it crashed? Check the output of ps to see if you have any instances of iproxy running on the machine you are using to run idb. It could be that an old process is running and blocking the port.

Also, are you sure you have the SSH daemon running on the device?

@dmayer I am getting the following error while connecting to a device.

Does idb needs to have the device jailbroken?
