Cannot download the home brew package due to a certificate issue

[y-kim]

The system doesn't trust certificate of https://objects.githubusercontent.com/.
I created a mirror server which serving the home brew package as well. In that case, there was no problem.

Device name: AN-US800K UHD Box
Firmware Version: 03.50.20
Box Version: 3.5.0-43915
