Questions about jetson-inference compilation

I want to compile jetson-inference. I have downloaded it on TX2.Then I operate on the official steps:

$ git clone
$ cd jetson-inference
$ mkdir build
$ cd build
$ cmake ../

Then I meet the problem “connecting to ||:443 failed: connection time out”.I refer to Comment=5195914

But I am not able to link to Nvidia box or google drive,what should I do?


Could you check your network functionality first?
We can successfully open the NVidia box and the google driver link below:
