Error On Reading Instantaneous Profile of L&T Meter using Gurux.DLMS.Python

I have used Gurux.DLMS.Client.Example.python to read data of L&T meter using media: "net" and authentication: "low".

When I tried to Instantaneous Profile, it gets failed for read by "readRowsByEntry" and  "readRowsByRange" and  it is giving me error shown below.

-------- Reading 7 1.0.94.91.0.255 Instantaneous Profile
Entries: 1/1
Error readRowsByEntry ! Failed to read first row: Access Error : Device reports Read-Write denied.
Error readRowsByRange! Failed to read last day: Access Error : Device reports a temporary failure.

When I am trying to read BlockLoad Profile I am successfully getting response from "readRowsByRange" Below is output.

-------- Reading 7 1.0.99.1.0.255 BlockLoad Profile
Entries: 2730/4320
Error readRowsByEntry ! Failed to read first row: Access Error : Device reports a temporary failure.
