I occasionally tether my phone to my laptop using bluetooth and have found 
that establishing a connection can be quite temperamental.  Rebooting the 
phone or disabling/enabling its bluetooth service usually helps get a response 
from it.

This is typically obtained when the device is not set to be discoverable.  
Check that they both are.  If you have restarted/reset either you may need to 
set them back to discoverable.

Have you set up the correct device MAC address in /etc/bluetooth/rfcomm.conf 
and restarted it?  If yes then this may be a matter of misstyping the pin?

I don't have bluetoothctl here to know what it does, but I use l2ping, 
hciconfig and sdptool first to make sure that I can see and read the device I 
am trying to pair with.  If you have indeed managed to pair the two devices 
you would not be getting the above connection errors, unless the radio signal 
broke down after pairing, due to e.g. weak signal or electromagnetic 
interference from some external source.
