From GameWatcher: “Ghost Recon Breakpoint is currently undergoing its first widespread beta test, and in true beta fashion, players are struggling with a number of connectivity errors. 40002 and 30086 seem to be most pervasive.
Down below, you’re going to find a few potential fixes for errors 40002 and 30086, though we can’t exactly guarantee they’ll resolve your problem. Namely, it might not even be related to your setup at all, but due to server outages and other network-related issues.”
