Water dispenser and ice maker not dispensing water

I don’t actually know the age of this model, it was in the house when I purchased it several months ago.

Anyway, just today, I found out that the water dispenser on the door is not dispensing water AND the ice maker is not receiving water in order to make ice. I tracked all of the lines to the fridge and the water is definitely making it TO the fridge, it’s just not going where it’s supposed to once there. Does anyone have any ideas on what the cause is and/or if it’s an easy fix?
