New recess lights wont work

So I replaced 6 older canned halogen recess lights in my living room with six new 6" recess led lights (canless version). That worked out beautifully.

After that, I brought eight more 4" recessed lights (can-less again) to replaced the older canned halogen recessed ones in the bathroom. The bathroom only has a black and white wires and no ground to the halogens. The wires are stranded and not solid, so instead of using the push connect I just used a wire nut. I installed as normal and didnt do anything with the ground since there is no ground. Not sure if thats the issue but the lights wont turn on. I tried tagging the white into the ground to see what that does but also nada. I know the switch is working because the green light is lit on the dimmer. There is power coming into the new lights too.. For diagnosis purposes, I disconnected the power to the chain, so that only light # 1 and light #5 has power but still light #1 and light #5 still wont light up.

I swapped out the switch to see if that was the problem but still doesnt work. The old lights work fine still if I out the old housing and lights back.

Any ideas? Here is the drawing of what I can see in the walls. I dont know how the light from #1 and #5 reach the switch but I assume they are piggtailed in the wall together?
