This sounds exactly like this entry in docs/KNOWN_BUGS
37. Having more than one connection to the same host when doing NTLM
authentication (with performs multiple "passes" and authenticates a
connection rather than a HTTP request), and particularly when using the
multi interface, there's a risk that libcurl will re-use a wrong connection
when doing the different passes in the NTLM negotiation and thus fail to
negotiate (in seemingly mysterious ways).
