What is an Error 42?
Error 42 indicates an interruption in your connection to the game's account servers, which handle everything from login to numerous social systems in the game, including guilds and chat. The error can occur both before and after you've already logged into the game, preventing you from logging in or disrupting your access to certain systems if you're logged-in when problems arise.
On the client-side, the error is most often caused when a network problem disrupts your connection to the account servers. On the server-side, the error can be caused when the servers themselves are experiencing network issues.
Note (April 17, 2018): Russian users are currently experiencing an Error Code: 42:1000:7006:1232 when attempting to access the game. This is due to local ISP issues or issues related to your ISP blocking your connection to the Amazon Web Services (AWS) servers. You can contact your ISP for more information or try connecting through a VPN to continue playing the game.
How do I fix an Error 42?
Network issues on the server-side are often resolved within a few minutes. If this is not the case, here are a few steps you can take to troubleshoot the issue:
Completely exit the game and close the client. Wait five minutes, then re-launch the game and try again.
Reboot your PC. Giving your computer a chance to reset and reboot can help address numerous issues that might impact your connectivity to the game.
Reset your router and modem. Rebooting your modem can fix connection problems, improve slow connections, and clear out any issues stored in the memory of your router.
Temporarily disable any security software such as Norton, AVAST, AVG, or McAfee, and then re-launch the game.
If these basic steps do not help, try these more advanced troubleshooting steps:
If this does not work, adjust the 'security' setting within your firewall settings. Lowering this setting to 'medium' or 'low' will often clear up connection issues.
