Locate Features Along Routes generates blank tables.

I'm using Locate Feature Along Routes to locate my points on a route all defined as shape layers on same coordinate systems. But it doesn't work. The points won't be located and the generated table is blank.

as it indicates, how close are the points to the line?

[SiamakFarahmand]

Around 5 meters. But I have played with radius, it didn’t help.

and coordinate systems are the same... which isn't the same as them showing up onscreen in the same place, because of projection-on-the-fly

When crazy things occur using points along a route, here in this thread I mentioned some things I try.... 

https://community.esri.com/thread/214168-create-route-event-layer-layer-doest-show-up 

The most common issues I see when I use the tool:

1.  No ESRI recognized ObjectId in the event/overlay layer

2.  Projections not the same

3.  No valid route layer

4.  Screen refresh lag ... some times at a range of specific zoom levels the data will not display or disappears.

Hope some of this helps...

I had the same problem with a point feature I was trying to locate on a route.  It sat 100% directly on the route line, but for some reason the search radius had to be set to something insane for it to find the point.

Note: If you are doing this with standard point and line layers, then for the tool to work you need to convert your line feature class to a recognized "route layer" and use that instead. To do that, run the Create Routes tool.
