I've got an Avallo Accumonitor in my cabinet that measures about 2X2X6. I would say it uses 2 cups of water a week in the winter. I open it about twice a day. So accept that you are going to use a bit more water in the winter. I probably use 3-4 times as much in the winter.

That said, I would use black tape to wrap the corners of the cabinet on the outside. If your humidity loss still seems excessive, there has to be a leak at a seam. I would cover all of the seams and see if that helps. Don't use aquarium cement until you know exactly where the leak is. Plus, I would be hesitant to return your cigars to the humi after using the cement. It has a strong vinegar smell that could easily taint you stogies.
