### All routes for my custom model fail
This could mean that either your custom model made some of the roads near the start and destination inaccessible,
then usually we return a PointNotFoundException with the point_index with the "location snap" problem.
Or, the custom model made a route between your start and destination impossible, then we return a ConnectionNotFoundException. This happens e.g. when you exclude tunnels,
ferries or motorways but all routes between start and destination have these road attributes satisfied, i.e. we cannot find a route.
**Solution for both cases**: relax your custom model and e.g. instead of excluding certain road attributes via `"multiply_by": "0"` you should try to use `"0.01"`.
