Additionally, the right solution can depend on the cause of the problem, so some diagnosis is required. With that, here are some techniques you may try to solve this DayZ error:

Run Discord as Administrator

Running Discord and DayZ at the same time may cause some issues, particularly the occurrence of the WaitAuthPlayerLoginState error message. Follow these steps to help fix this issue:

• Search for the Discord shortcut on your system
• Right-click on the Discord shortcut and select “Run as administrator”
• Select “Yes” if prompted for confirmation
• Launch DayZ normally and check if the problem disappeared or persists

Verify Game File Integrity

Downloading a DayZ update perhaps resulted in an incomplete set of files, causing the WaitAuthPlayerLoginState error. Verify the game’s file integrity to let it download any missing files needed for the game to run properly. If you find that missing files are the cause of the error message, follow these steps:

• Launch Steam and log in to your account
• Navigate to your Steam game library and right-click on DayZ at the left sidebar
• Choose “Properties” from the context menu that appears
• In the game’s Properties window, select the “Local Files” tab, and then click on the “Verify Integrity of Game Files” button
• Wait for the verification to complete and launch DayZ normally to check if the problem has disappeared or persists

Delete a Corrupted Player Profile

Sometimes, a corrupted player file can cause errors when trying to log into DayZ. Note that deleting this character profile can cause in-game losses. So, ensure that a corrupted file is the cause of the WaitAuthPlayerLoginState error message before following these steps:

• Close DayZ and run Task Manager to ensure it’s not running in the background
• Open File Explore and navigate to “C:\Users\[Your Username]\Documents\DayZ”
• Open the location and locate the “DayZ” folder
• Confirm the deletion when prompted
• Attempt to run DayZ normally and check if the problem disappeared or persists

Note: Deleting the folder will only move it to your PC’s trash bin. Press SHIFT+DELETE to remove the folder from your system permanently.

Disable In-Game Overlays

Overlays, such as the NVIDIA GeForce Experience, may cause login conflicts when trying to open DayZ. If so, temporarily disable these overlays to check if it fixed the error. Note that the steps to disable a specific overlay depend on the software. Here are the steps to disable the Discord and NVIDIA GeForce Experience overlays from your PC:

Disable the Discord Overlay

• Open the Discord app and click on the gear icon near the headset icon at the lower left of the screen
• Once the User Settings menu is open, select “Overlay” from the left sidebar
• Search for “Enable in-game overlay” and turn off that option

Disable the NVIDIA GeForce Experience Overlay

• Click on the upward-facing arrow next to the clock at the lower right of your desktop to open the system tray
• Search for the NVIDIA Settings icon and right-click on it
• Select NVIDIA GeForce Experience from the context menu
• In the NVIDIA GeForce Experience app, select the gear icon at the top right corner of the window
• With the Settings opened, navigate to the General tab
• Search for the “In-Game Overlay” option and turn it off

If the above methods don’t work, you may need to uninstall and reinstall DayZ. However, if the problem persists after the reinstallation, consider sending Bohemia Interactive, the game’s developers, a message directly.
