Https://gitlab-master.nvidia.com is not accessible

I am following instructions from this link to setup cuMAC,

When I tried to do “git clone --recurse-submodules https://gitlab-master.nvidia.com/gputelecom/cumac”, I got this error “Could not resolve host: gitlab-master.nvidia.com
Anyone knows what’s going on with “gitlab-master.nvidia.com
Thanks a lot.

It looks like you have already posted in the correct place for this on the aerial private forum. Someone there will hopefully be able to help soon.
