Not able to configure TX2 development kit

Team, I am trying to configure my new TX2 development kit and could see issues with downloading jetson pack with SDK manager.
SDKMANAGER version used: 1.1.0.6343
Jetson pack: 4.3,4.2, or 4.4 are tried
Always end up in below error in step 02 process:
“Could not load the nvidia sdk details. Failed to get configuration file from the server. Please check your network connectivity”.

A quick resolution helps
