hub: Module downloading failed - No address associated with hostname (tfhub.dev)

I am trying to run this Semantic Similarity with TF-Hub Universal Encoder

But in the module initialization, downloading is failed with

URLError: <urlopen error [Errno -5] No address associated with hostname>

Also tried in my local machine and a remote machine that is in another network, both hits the same error.

Seems the downloading server is down?

Full log is attached in here:

Also tried wget 'https://tfhub.dev/google/universal-sentence-encoder-large/3?tf-hub-format=compressed' -O /tmp/module.tar.gz in my local and it is not working either.
