"Game Error G99" is an error message you can get in H1Z1
Description[edit]
MALFUNCTION:
There is an issue connecting to the login server. The login server may be down for maintenance. Please try again a little later. Be sure to check the forums for announcements on planned server shutdowns and estimated downtimes. If there has been no notification of a server shutdown, validate your game files from the LaunchPad and make sure that H1Z1.exe, awesomiumprocess.exe and launchpad.exe are all set as exceptions in your firewall/antivirus program(s). The login server may still be shut down without notification, but running through these steps will ensure that the problem is not on your end.
Cause[edit]
Overload on login servers
Solution[edit]
Wait a few minutes and try logging in again
