Failed to get configuration file from the server. Please check your network connectivity

I downloaded the SDK Manager but when I got to Step 2. this error shows up;
Oops! Could not load NVIDIA SDK Details. Fail to get configuration file from server. please check your network connectivity.

My network is fine. my location is in Korea if that is helpful…

Dear @youhb0831,
We have CDN outage and we are working on it. Could you please clarify if the used platform is DRIVE or Jetson?
