We are working on it. I don't know why these things have to be so complicated. Thanks for notification though.

Since a couple weeks ago, accessing the API fails on HTTPS negotiation when using urllib.request (Python native), wget, and curl.
I can reproduce it on various systems, including Google Colab, the behaviour is the same.
(It seems to be that the URL is redirected to https mode, try curl without -L to see the redirect.)

Apparently there's something off with the server's certificate chain, see https://www.ssllabs.com/ssltest/analyze.html?d=neuroml-db.org (though browsers don't whine at all). But until recently scripts were working fine.

Overriding https authentication is viable, but it's a wrinkle for tutorials.

import urllib.request; # import ssl; ssl._create_default_https_context = ssl._create_unverified_context
urllib.request.urlretrieve(f'http://neuroml-db.org/GetModelZip?modelID=NMLCL000625&version=NeuroML', 'cell.zip')

fails with SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1007)

wget -o cell.zip http://neuroml-db.org/GetModelZip?modelID=NMLCL000625&version=NeuroML

fails with

ERROR: cannot verify neuroml-db.org's certificate, issued by ‘CN=InCommon RSA Server CA 2,O=Internet2,C=US’:
  Unable to locally verify the issuer's authority.
To connect to neuroml-db.org insecurely, use `--no-check-certificate'.

curl -o cell.zip -L http://neuroml-db.org/GetModelZip?modelID=NMLCL000625

also fails with SSL certificate problem: unable to get local issuer certificate.

@spanag can you send me a direct email at sharon.crook@asu.edu if you don't mind? My IT person has some questions in trying to fix this quickly.
