The Nightly version fails to establish a netplay connection; the session drops immediately upon joining. The core tested was fbneo with the game Street Fighter II: Champion Edition.

No source file, test, bisect result, or log output is provided. First reproduce the drop with the fbneo_libretro core, SF2CE, and the 1.22 nightly on the reported Windows and Linux setups, then compare against stable while collecting logs. Done means a joining player's netplay session remains connected in the reported scenarios.
