Ask HN: How do you know if you have a product problem or a distribution one?

I keep building products, ideas etc that are I think are good and solve people's issues at least what I see them complain about but it doesn't result in any meaningful traction. When I ask people to use something its either non-existent or you just get ignored even though it solves the issue they describe.

Do I have a distribution/outreach issue or am I just building crappy stuff nobody wants ?

I do all the recommended steps of getting an ICP and then doing difficult things that don't scale but it goes nowhere.
