DayZ Error Codes
Fast, readable reference for server and client warning codes. Search instantly, filter by category, and apply practical fixes without digging through noisy forum threads.
Documentation Disclaimer
This is not a complete list of every DayZ warning/error code. Finding and validating all codes is difficult, so this hub currently includes the most reliable entries I could verify so far. Official documentation does not publish an exact root-cause tree for every code path, so this page combines official code naming with support guidance and reproducible community evidence and will be expanded as more codes are discovered and confirmed.
Admin / Server Action
2 entries0x00040010
ADMIN_KICK
Player was removed by a server administrator or admin system (and can occasionally appear during scripted pre-restart kick routines).
Common Causes
- Manual admin kick
- Rule enforcement
- Automated moderation
- Automated pre-restart player kick routine on some community servers
Recommended Fixes
- If a restart was announced, wait and reconnect after the server is back up
- Contact the server admin if needed
- Review server rules

BattlEye / Client Response
1 entry0x000400F0
CLIENT_NOT_RESPONDING
Client failed to respond to BattlEye or related checks.
Common Causes
- BattlEye service/client path is blocked or not responding
- Service version mismatch or query timeout variants
- System/resource stalls that prevent timely BattlEye response
Recommended Fixes
- Verify game files and reinstall/repair BattlEye service
- Allow BattlEye executables in antivirus/firewall and remove blockers
- Relaunch and join via in-game browser if launcher direct-join fails
Client Crash / Runtime
1 entry0xC0000409
PROCESS_CORRUPTION_FAST_FAIL
Windows raised a non-continuable fast-fail exception (0xC0000409), indicating the process was considered corrupted and terminated immediately.
Common Causes
- Critical runtime corruption detected by Windows fail-fast handling
- Injected/blocked third-party files or security tooling conflicts in the game process path
- Corrupted game/runtime files that destabilize startup or in-session execution
- Corrupted or outdated mods causing client instability during load or gameplay
Recommended Fixes
- Verify DayZ files in Steam (Installed Files -> Verify integrity of game files)
- Repair BattlEye path and ensure BEService/launcher executables are not blocked by antivirus or firewall
- Update all required server mods and repair/re-download corrupted Workshop mod content before reconnecting
- Check for unexpected injected DLLs in the game directory (for example d3d9.dll, dxgi.dll, dsound.dll) and remove non-required hooks/overlays
- Reboot and retest with minimal background software to isolate third-party conflicts
Login / Player State
2 entries0x00040030
LOGIN_MACHINE_ERROR
An error occurred during the login process.
Common Causes
- Server-side session initialization issue
- Temporary backend failure
Recommended Fixes
- Reconnect
- Try another server
0x00040031
PLAYER_STATE_TIMEOUT
Player data failed to load in time.
Common Causes
- Authentication/login state timed out on server handshake
- Backend/server load during player auth
- Client sync delay during login state transition
Recommended Fixes
- Retry after server restart or lower-load period
- Verify files and relaunch before reconnect
- Try another server to isolate whether the issue is server-specific
Mods / Verification
1 entry0x00040074
VE_EXTRA_MOD
Client has a mod installed that is not present on the server, or mods failed to load/validate in time before server verification.
Common Causes
- Client has extra mods the server doesn't run
- Mod was recently removed from server but client still has it
- Client launched wrong mod set for this server
- Mod manager activated mods not in server's active list
- Mods stored on slow storage (external HDD ~80-120 MB/s) and didn't load/validate in time during login
- Mod verification timeout due to system resource constraints or storage I/O bottleneck
Recommended Fixes
- Disable extra mods on your client that aren't on the server
- Verify server's active mod list before joining
- Use mod manager to synchronize your mods with server requirements
- Create a separate profile for this server with matching mods only
- Move game and mods to internal SSD (at minimum) or Thunderbolt SSD for consistent fast loading (90-98% success rate if HDD was the bottleneck)
- Avoid external HDDs (USB suffers from high latency and poor seek time with thousands of small mod files)
- Close background applications to free up system resources during mod loading
Network / Connection
3 entries0x00040004
NETWORK_TIMEOUT
Client timed out while communicating with the server.
Common Causes
- Slow storage such as HDD or external USB drive
- Network instability or packet loss
- Large mod packs loading too slowly
Recommended Fixes
- Use a stable wired connection and reduce packet loss/jitter
- Restart router/modem and renew local network stack
- Verify game files through Steam
0x0004000A
UNSTABLE_NETWORK
Connection to the server is inconsistent or fluctuating.
Common Causes
- Unstable Wi-Fi or congested local network
- High latency and packet loss between client and server
- Transient ISP or route instability
Recommended Fixes
- Use Ethernet instead of Wi-Fi where possible
- Restart network equipment and retry on a cleaner route
- Test another server/region to isolate route-specific instability
0x0004000B
SERVER_SHUTDOWN
The server is shutting down or restarting.
Common Causes
- Scheduled restart
- Server crash
- Maintenance
Recommended Fixes
- Wait for the server to come back online
- Reconnect after restart
Sources
Respawn / Identity
2 entries0x00040050
INIT_RESPAWN_IDENTITY
Issue initializing player identity during respawn.
Common Causes
- Server-side respawn state issue
- Character identity initialization failure
Recommended Fixes
- Reconnect
- Retry after server restart
Sources
0x00040051
RESPAWN_IDENTITY_ERROR
Respawn identity process failed.
Common Causes
- Identity state corruption
- Server-side respawn issue
Recommended Fixes
- Reconnect
- Try again after restart
