The optional private curl transport now advertises the hybrid X25519MLKEM768 TLS group alongside X25519, P-256 and P-384. This addresses TLS connection failures on proxy paths that reject a classical-only ClientHello. The transport continues to offer only h2 through ALPN.
Install or upgrade with:
pip install -U "instagrapi[curl]==2.18.20"Enable the transport with Client(private_transport="curl"). Authentication handling and the default transport are unchanged.
Includes #2788.
