Reg: Unauthenticated error with different disconnection reason codes after the IOT hub connection is established

[vasoyanikhil]

Hello All,

1. I am deleting the device from the Azure IOT when device is offline, and after power ON device I am getting the error reason code as per the below sequence.
   IOTHUB_CLIENT_CONNECTION_BAD_CREDENTIAL 
   IOTHUB_CLIENT_CONNECTION_NO_NETWORK
   IOTHUB_CLIENT_CONNECTION_BAD_CREDENTIAL
   IOTHUB_CLIENT_CONNECTION_NO_NETWORK

Is it correct reason sequence? But It should be send only IOTHUB_CLIENT_CONNECTION_BAD_CREDENTIAL error right?

2. When the SAS token expired, I was getting an error  code from the device as per the below sequence.
   IOTHUB_CLIENT_CONNECTION_NO_NETWORK -> 4
   IOTHUB_CLIENT_CONNECTION_BAD_CREDENTIAL-> 2
   IOTHUB_CLIENT_CONNECTION_NO_NETWORK -> 4
   IOTHUB_CLIENT_CONNECTION_BAD_CREDENTIAL-> 2
   IOTHUB_CLIENT_CONNECTION_NO_NETWORK -> 4

Expected : Azure IOT should send error reason code IOTHUB_CLIENT_CONNECTION_EXPIRED_SAS_TOKEN.

Any one can help with the above two questions. 

Note: I am using MQTT protocol.
