If you encountered a Communication error in Daemon X Machine, check if your Internet connection is slow. You can use any of the free Internet Speed testers to find that out, in case, the bandwidth is low, restart your router and if that doesn't help, contact the ISP. However, one of the major reasons for this issue is a bug in Epic Games Launcher, you can update the launcher or download the latest version of the same from store.epicgames.com.
