Symptoms

UPlay, or Ubisoft Connect, is not able to connect to the Ubisoft servers, so it crashes with this message:

Reproduction

Launch the game and login to UPlay.

I've also installed the latest Ubisoft Connect in the game's wineprefix, but since that version tries to connect before login, it immediatly crashes with the same message.

No source file, test, or code entry point is identified in the report. Begin by reproducing the Ubisoft Connect login failure with the listed Proton versions and reviewing the linked system information; a useful result would identify a confirmed cause and a targeted fix or documented workaround.
