No power in ceiling light fixture box

I was replacing a ceiling light fixture this afternoon when all of a sudden there was no more power in the box. there are 3 sets of wires in the box: power coming in, another set of wires going out, and a third that runs to the wall switch. Nothing in the entire box is giving any power. I checked all the breakers and none were tripped. I even switched every breaker off and on again to be sure. Every other light fixture and outlet in the house is still working, which is whatís most baffling about this. It appears this light is in the mid-stream, as if it was the last thing on the circuit there would only be two sets of wires in the box (one coming in and one going out and back from the switch).

Iím at a completely loss for what could be happening. The only thing I can think of is if there is some hidden box in my ceiling where a wire has come loose, but I still feel like something else should have no power since power canít be leaving the box. Iím attaching a photo of the wire configuration. The black wire at the top left is between the fixture and the switch. The bottom left cluster has the white wire going to the switch and the two blacks from the other sets of wires. The other two whites are joined. When I pulled off the old fixture. The cluster of 3 was wired and tucked up in the box. The light was wired to the single black wire and the two whites.

Anyone have a clue what could be happening here? Itís baffling to me. Thanks in advance.

Welcome to the forums.

Nothing in the entire box is giving any power.
It's usually easier to find a loss of hot rather than loss of neutral.
Did you check from hot to ground in that box ?

You should know everything on that circuit. More than likely there are things on it that are still working. Your problem will be at the last working device or the first dead one. If you don't what is on that circuit..... you will need to figure it out. There is no easy way around it.
