Cannot download with NTLM authentication if frozen with cx_freeze

[dglent]

Hi

I have a problem when i run my code as frozen script.
No frozen it works
I am in entreprise proxy and the server is inside

requests version 2.21.0
requests_ntml version 1.4.0

session = requests.Session()
session.auth = HttpNtlmAuth(username, password, self.session)
req = session.get('http://nnnnnnn//nnnnn')

<class 'ValueError'>
unsupported hash type md4

Do you have any idea to workaround this problem ?
Thanks n advance

Looks like its your environment that has a problem, can you double check by doing this on python shell

>>> import hashlib
>>> hashlib.new('md4')

I have this output (same in python 2.7 installation)
The error occurs only when the script is frozen...

>>> import hashlib
>>> hashlib.new('md4')
<md4 HASH object @ 0x004B08A8>
>>>

Ok, it needs the dll files in the frozen directory
