No water from door

My door water does not flow. It’s still making ice and the water flow to the ice maker works fine. I thought the line froze and I turned the frig temp up a notch and the bottom drawer temp up and let it sit for 24 hours. Still no water. I have replaced the filter and tried to let the water run. The Filter blows off with pressure when I take it off and the filter does seem to fill with water.

How do I start to track this down?

Thanks.
