Can't build any route with error "Connection between locations not found. Different subnetworks 3 vs. 1"

What does “Connection between locations not found. Different subnetworks 3 vs. 1” mean?
It refuses to build any simplest route, like 2 points on the same street in 30 meters from each other. And no block_areas applied.

This happens when you calculate a route between two different landmark subnetworks. What are you trying to do?

Hi @easbar - what is the size of a landmark subnetwork?

GraphHopper includes this splitting: https://github.com/graphhopper/graphhopper/blob/master/core/src/main/resources/com/graphhopper/routing/lm/map.geo.json

Why do those sub-networks even exist? Why can’t we build a route between, say, Minsk and Moscow? And border regions are also unreachable
