If your water line connector is fine, then Run the machine in service diagnostics mode. Your tech sheet should be behind the lower grill on the right side or tapped to the bottom of the machine. Once you enter diagnostics mode use the test chart on the tech sheet to test the ice maker and fill valve.
Having the same problem -- providing water just fine, doesn't seem to be a leak (no water on floor near fridge) but it's not making ice. Ice maker is turned on and there is no blockage. Can you provide a link to the tech sheet? We cannot find one on our fridge anywhere to figure out how to enter diagnostics mode and run the tests.
