The few times I've serviced refrigerant I had to turn the can upside down to get it in the system. Have you tried that? When making the connection open the servicing valve slightly and verify you have gasious flow before you make the connection or else you'll be putting air and humidity from the servicing hose in the system. Verify the seals on both ends of the service tube and valve are in good shape. Make sure the connection snaps into place. Once connected fully open the valve and turn the can upside down for several seconds at a time.
