How to Fix VEIN Server Crashing or Freezing After Editing Config Files Print

If your VEIN server starts crashing, freezing or refusing to boot after editing Game.ini or Engine.ini, the cause is almost always an invalid config entry or a misplaced CVar. This guide explains every known reason VEIN servers crash after configuration changes and how to fix them safely.

Works on all HostByte VEIN servers. Updated for VEIN v0.022h8

Step 1 Check if the Server Started Correctly

Open your HostByte Game Panel and look at the console output.

If you see messages like:

Fatal error
Unknown console variable
Failed to load Engine.ini

then the crash is caused by a configuration mistake.

VEIN is very strict with formatting, incorrect section headers or unknown CVars will crash the server immediately.

Step 2 Confirm CVar Placement Is Correct

Most server crashes happen because CVars were placed in the wrong file. Always follow these rules:

All vein.* settings go in Engine.ini

Vein/Saved/Config/LinuxServer/Engine.ini

[ConsoleVariables]
vein.Zombies.Health=60
vein.Loot.RespawnTime=3600

All GS_* settings go in Game.ini under ServerSettings

[/Script/Vein.ServerSettings]
GS_HungerMultiplier=1.0
GS_ThirstMultiplier=1.0

If a vein.* CVar is placed inside Game.ini, the server may crash or ignore the entire file.

Step 3 Check for Missing or Incorrect Headers

Incorrect headers are the second most common cause of VEIN crashes.

These must match exactly:

[/Script/Engine.GameSession]
[/Script/Vein.VeinGameSession]
[/Script/Vein.ServerSettings]
[OnlineSubsystemSteam]
[ConsoleVariables]

If a header is misspelled, duplicated incorrectly or placed inside another section, VEIN can fail to load.

Step 4 Remove Unsupported or Mistyped CVars

If you typed a CVar that does not exist in VEIN v0.022h8, the server may fail to boot.

Examples of issues:

• Typos such as vein.Zombeis.Health
• Extra spaces or invisible characters

Step 5 Undo the Last Change You Made

If the crash happened immediately after adding a new line, simply remove that line.

Recommended rollback process:

1. Stop the server
2. Remove the last added CVar or setting
3. Start the server again

If the server boots normally afterward, the issue was caused by that specific change.

Step 6 Restore a Working Backup

HostByte automatically stores backups when the server is installed. You can restore them with:

• Game Panel File Manager
• Download backups that you made with the panel

If you want the server restored manually, open a ticket and our team can restore the most recent working configuration.
