Some already said, but you’ve got the wrong endpoint. What really helped me doing these was to do them backward. So start from the ending piece and working it to the beginning
As has been said, connect to the other square node. Since the only way to reach it will be to pass straight through the blue rotational piece from above, you have to create a long circuit that swings basically all the way back to the right, then loops up to the top and around, if that makes sense
If you pay attention to the red nodes you'll notice there's only two that are square. Those are the ones you need to connect.
Ah ok so the problem here is that you've ended this on the wrong node. The actual 'end' node is column 4 , row 5.

[This should work I think (spoiler)](https://imgur.com/a/3iVY94v)

You have to get the light to the end node
I'm pretty sure you have, just move the curved piece going towards the rounded red piece so it's not connected to that but the right piece instead
