Comment (by qichaoshen):

 I think the root cause is invalid http range get request starting from the
 file size value.

     We can find that the http resource size is 207500195,and the http
 range get request starting from the 207500195, so the Server return status
 code 416.
      And this problem can be reproduced by the following command:
