Graphopper not able to find route

Only 2/6 are routed. If analyzing input data then 5-6 points should be routed. Can not find any reason why this happens.

The restriction for the vehicle is likely too tight. If you remove or increase the time window:

      "earliest_start": 1581314400,
      "latest_end": 1581354000,

it will work.
