How to debug network analyst problems - endpoint routes work, vertex do not

I have a feature class that is comprised of roads in a country. I've created a network that includes this feature class with the following relevant options:

1. Vertex connectivity (not end point).
2. No elevation modeling
3. Length as cost attribute is the only attribute
4. Global turns

When I attempt to complete analysis tasks such as OD matrix or even Route, the only paths that are found are those where the points are on the same edge or on edges connected via endpoint. I've taken a good look at this and as soon as I place the next point of the route onto an edge that is joined by intersection, the error dialog pops up saying there is not path to that next point.

What should I do next?
