If your DayZ server fails to start or stops immediately after launch, this guide will help you identify and resolve the issue using the FinnishHost Game Panel.
Step 1: Check the Web Console
After clicking Start, open the Web Console right away. Look for red text or error messages such as:
Server init failed
Cannot open file 'serverDZ.cfg'
Addon requires key not found
Missing addons detected
These indicate missing files, invalid mods, or configuration problems.
Step 2: Verify Configuration File
Go to Configuration Files → serverDZ.cfg and check for missing or broken entries.
A minimal working config should look like this:
hostname = "My FinnishHost DayZ Server";
password = "";
passwordAdmin = "StrongAdminPass";
maxPlayers = 40;
verifySignatures = 2;
forceSameBuild = 1;
Ensure all quotation marks " " are properly closed and there are no missing semicolons ; at the end of lines.
Step 3: Validate Command Line Parameters
Open Commandline / Startup Parameters and confirm your startup line is complete:
-config=serverDZ.cfg -port=2302 -profiles=Profiles -dologs -adminlog -netlog
If -config points to the wrong file or directory, the server won’t launch.
Step 4: Check for Mod or Key Issues
If you’re using mods, a missing or invalid key file is a common cause of startup failure. Check the Web Console for lines like:
Signature check failed for mod XYZ
To fix this:
- Open the mod’s folder in File Manager.
- Copy all
.bikeyfiles from the mod’sKeysfolder to your main/keysdirectory. - Restart the server.
Step 5: Test Without Mods
Remove all mods temporarily to isolate the problem:
- Open Commandline / Startup Parameters.
- Remove everything after
-mod=. - Save and start the server again.
If the server starts successfully, add mods back one at a time to find the cause.
Step 6: Validate Game Files
Click Update Server Files in your FinnishHost panel. This re-downloads any missing or corrupted DayZ server files via SteamCMD.
Step 7: Check for Incorrect File Paths
Ensure the serverDZ.cfg and battleye folders are in the correct directory:
DayZServer/
If these were moved, the startup command can’t locate them and will fail.
Step 8: Reinstall (Last Resort)
If all else fails, use the Reinstall option in your control panel. This refreshes all core files and returns the server to a clean state without mods.
