[ x] that I haven't found an existing compatibility report for this game.
[ x] that I have checked whether there are updates for my system available.
Symptoms Attempt to launch AC Odyssey, Ubisoft Connect starts up at "Initializing" but ends with an error - "Connection Lost - A Ubisoft service is currently unavailable. Please try again later."
But no matter how long you wait, it never works. I've been playing this game for the last few years with little to no issues on Linux - over 500 hours, but now it won't launch. steam-812140.log systeminfo.txt
