Dead by Daylight errors and common problems

Game crashes: Old drivers, damaged files or background apps

Means

For crashes, error codes and poor performance on PC, Behaviour asks players to check the hardware, the connection, drivers, Windows and the game files.

First step

Check that your PC meets the minimum requirements. All steps

Keeps disconnecting: Weak Wi-Fi, router or DNS trouble

Means

Drops from matches and other connection trouble usually come from a weak Wi-Fi signal, a slow line, the router or blocked traffic on your network.

First step

Use a wired connection, or move closer to your router. All steps

Can't join a match: Moderate or Strict NAT limits connections

Means

If you can't join matches or crash during matchmaking, your NAT type may be the cause. Moderate and Strict NAT can only connect to some players, while Open gives the best connection.

First step

Open Behaviour's NAT page and pick the guide for your platform: Xbox, PlayStation, Steam, Epic or Switch. All steps

Matchmaking locked: Disconnection penalty after leaving matches

Means

Leaving a match in any way counts as a disconnect, even a crash or an internet outage, and it locks matchmaking for a while. Behaviour does not take appeals for these penalties.

First step

Wait for the timer to run out, since early penalties are short. All steps

Game Security Violation Detected: RGB lighting software conflicts with EAC

Means

Behaviour says this message often shows when software that controls RGB lighting, like glowing fans or RAM, clashes with Easy Anti-Cheat.

First step

Find any app on your PC that controls RGB lighting. All steps

Error Code 130: Servers busy with too many logins

Means

Error 130 means the servers are under heavy load because many players are trying to start the game at the same time.

First step

Wait 15 to 30 minutes, then launch Dead by Daylight again. All steps

Error Code 107: Connection dropped and came back

Means

Error 107 appears after a network disconnect and reconnect. The cause can be your connection or router, or an outage on your platform's online services.

First step

Check the status page for Steam, Epic, Xbox, PlayStation, Nintendo or GeForce NOW. All steps

Launch Error: Anti-cheat blocks an outdated driver

Means

Since a security update in July 2026, the game can refuse to start when it finds an outdated driver or tool. Common ones are RGB, overclocking, hardware monitoring, BIOS and maker updater utilities.

First step

Read the error to see which driver or program it names. All steps

Untrusted System File: Windows system files are damaged

Means

This error can appear when some of your Windows system files have become corrupted.

First step

Make sure your copy of Windows is genuine and fully updated. All steps

Version Mismatch: You and your friends run different versions

Means

This error shows when you and your friends are on different versions of the game, which happens most often right after a new patch.

First step

Update Dead by Daylight to the latest version. All steps

EAC Error Code 4: Easy Anti-Cheat could not verify the game

Means

You get kicked because Easy Anti-Cheat can't confirm your game is genuine. Behaviour notes this code can also point to failing RAM.

First step

In your Steam Library, right-click Dead by Daylight and open Properties. All steps
