Normally in Network analyst and route detection it has to find the shortest and efficient way.But here in my work I can see that it does not find the best choice.I wonder why it chose the longer path ? I have to mention that I am working on geological part of an area and I want to know the shortest connection between available fractures! Would it be because lots of vertices? or anything is wrong there that it cannot solve the route? Below you can see one of the examples of my project!
