Quick solutions

EAC Authentication Timeout / EAC Disconnected

1. Launch Rust from your Steam library, not from the game folder.
2. Steam → Rust Properties → Installed Files → "Verify Integrity of Files".
3. Open the game folder and run EasyAntiCheat_EOS_Setup.exe → «Repair Service».
4. Restart your PC and router. Temporarily disable VPN/overlays.
5. Check if the server is being updated.

Disconnected: Steam Auth Timeout

This is a Steamworks authentication timeout. Usually the network or Steam itself is to blame.

1. Restart Steam and Rust.
2. Steam → Settings → Downloads → “Clear download cache” (requires re-authorization).
3. Check the integrity of the files.
4. If the server is being updated or is unavailable, try again later or go to another one.

Unknown file version / Integrity error

Usually one of the game files is damaged or modified.

1. Look at the file path in the error message, delete it.
2. Check the integrity in Steam - the client will finish downloading the original.
3. Disable software that interferes with files: mod utilities, overlays, "optimizers".

Untrusted system file

A system library has been loaded that does not pass verification.

1. Command line from administrator: sfc /scannow .
2. Install the latest Windows updates.
3. Repeat Repair in Easy Anti-Cheat.

Rust won't start: "VCRUNTIME140.dll/MSVCP140.dll is missing"

Install Microsoft Visual C++ Redistributable 2015–2022 for x64 and x86. Restart your PC after installation.

Servers are not displayed in the list

1. Steam → Settings → “In game” → “Server browser pings per minute” ≥ 5000.
2. Update the client and the server itself to the same version.
3. Connect directly: F1 → client.connect IP:port .

Crash/freeze during Asset Warmup or when entering the server

1. Verifying files in Steam.
2. Update your graphics card driver (NVIDIA/AMD/Intel).
3. Increase the Windows paging file (virtual memory).
4. Close background programs and overlays.

The microphone does not work

1. Windows: Select the desired default microphone and disable unnecessary devices.
2. Steam: "Voice" → correct input and microphone test.
3. Rust: Check the input device and Push-to-Talk button.

"Incompatible version" / "Server is running a newer version"

Update the client. On the day of the forced wipe, the official server may be temporarily newer.

EAC/VAC ban

The ban is permanent. Erroneous waves are rolled back automatically. Appeals are submitted to EAC. Devbans for toxicity are not removed.

FAQ

Where to start if “nothing helps”?
Check files, Repair EAC, reboot PC and router. This closes most cases.

Is it possible to play with VPN enabled?
Better to disable. Some VPNs break authorization and connection to Steam.

Why can't the server be found via search, but the IP connection works?
Server browser restrictions and filters. Use direct connection.

Important: Error wording and behavior may differ on mod servers. Follow the basic steps first, then check the rules and versions on a specific project.
