Error 602 routing between 2 points

Hello,

I receive the info message 602 (Unable to calculate route) when I try to route these two points:

{ lat: 37.0918350220, lng: -8.2371664047 }

{ lat: 37.1019630432, lng: -8.2605485916 }

There are some other points that cause error 602, however all of these are valid and real points.

I'm using //open.mapquestapi.com/sdk/js/v7.2.s/mqa.toolkit.js and the route is free of conditions, beside the following options:

options: {

unit: 'k',

narrativeType: 'none'

}

Thank you.

Regards,
