Hi, could you help to provide more details about how you publish VRP service? Here are a few initial questions I have:
1. How did you publish VRP service? Did you run Solve Vehicle Routing Problem tool in ArcMap and then publish to ArcGIS Server? Or did you use publish routing services to publish VRP service?
2. What is the version of ArcGIS Server are you using?
3. What is the error code/ error message you get?
