OSError: [Errno 101] Network is unreachable

[scottyhq]

The bug

I noticed what seems like an intermittent network error. Simply waiting and re-running is a workaround, but wanted to report it anyways (hyp3-isce2 v1.0.1)

requests.exceptions.ConnectionError: HTTPSConnectionPool(host='urs.earthdata.nasa.gov', port=443): Max retries exceeded with url: /oauth/authorize?response_type=code&client_id=BO_n7nTIlMljdvU6kRRB3g&redirect_uri=https%3A%2F%2Fauth.asf.alaska.edu%2Flogin (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f59187f18d0>: Failed to establish a new connection: [Errno 101] Network is unreachable'))

To Reproduce

As mentioned, it isn't consistently reproduced, I ran the following when I encountered this:

python -m hyp3_isce2 ++process insar_tops_burst \
      S1_292377_IW2_20160314T020058_VV_C91D-BURST \
      S1_292377_IW2_20160407T020058_VV_EB2A-BURST \
      --looks 20x4 \
      --apply-water-mask false
