Error downloading/installing git repositories from behind a firewall

I am unable to install a library at the moment, I suspect this is due to our firewall.
but manually cloning the library works fine.

Edit:more info: this error started after we migrated from bitbucket to microsoft azure devops.
also if I edit the downloader.py file to accept 203 status:

line 41:
if 300<= self._request.status_code or self._request.status_code < 200:

a new issue occurs in the unpacker.
is there a workaround for this issue?
performing git clone works flawlessly but when trying to build a project that depends on this repository it fails with:
