OSRM Not showing routes!

I have installed an OSRM Backend server loally on my machine, now i want to show routes for a particular country say England. I downloaded .pbf file for the country. Then installed OSRM-Frontend locally as well. After making required changes to point to local backend server and running npm run, i can access OSRM fornt-end on another machine. It gets whole map but when i try to route over two point in England, it only shows markers but no route/polyline appears on map. I am also not able to access it over the same machine. Can any body suggest why this is happening.
