You have not screwed the connector on tightly enough....story of my life.

Sounds like you are not getting a good interface between the connector and the valve.

Presta or Schrader (Car type) ?
Make sure the pump head is configured for the right type of valve.

Let all of the air out of the tyre, and then use your thumb to push the valve as far through the wheel as possible, hold it here while you connect the pump.

Perhaps the pump is worn out and leaking air round the rubber seal. I would recommend a good quality track pump (the type that has a handle you push up and down rather like an old fashioned device for detonating explosives).as a lot of pumps specially cheaper ones are awkward to use and tend to leak air and you can't get the recommended air pressure into the tyre to make riding less effort.
