The Isle Evrima Server Troubleshooting

Fix common issues with your The Isle Evrima dedicated server — server not in browser, players can't connect, crashes, and performance problems.

Common issues and how to fix them on your The Isle Evrima server.

Server Not Showing in the Browser

Wait first — after a restart it takes 2–5 minutes for a server to register with EOS and appear in the browser. If it still doesn't show:

CheckFix
Server is runningCheck Console for errors. Server must show "Server listening"
EOS credentialsVerify Engine.ini has the [EpicOnlineServices] section with the right DedicatedServerClientId and DedicatedServerClientSecret. Without these, the server won't register
Unique server nameMake sure ServerName is set in Startup or Game.ini
Max ping filterIn the player's game Settings > In-Game, set max ping filter to 500–1000
Players on Evrima branchAll players must be on the evrima - public Steam beta branch, not Legacy

Players Can't Connect

Verify the server is online

Open the Console in the panel. The status should be green/running. Look for any errors in recent log lines.

Check version and branch

All players must be on the evrima beta branch in Steam (right-click The Isle > Properties > Betas). Both server and client must be the same Evrima version.

Verify ports

Confirm UDP 7777–7779 are accessible. Check the IP and port shown on Network in the panel.

Check password

If bServerPassword=true, players need the exact case-sensitive password.

Check whitelist

If bServerWhitelist=true, the player's SteamID64 must be in WhitelistIDs= in Game.ini.

Check server isn't full

If MaxPlayerCount is reached and bQueueEnabled=false, players are rejected. Enable the queue with bQueueEnabled=true.

"Data Acquisition Failed"

The most common client-side error in Evrima. Your server appears in the browser, but the client can't fetch its EOS session data when joining.

CauseFix
Server just restartedWait 1–2 minutes after the map finishes loading — EOS session registration takes 30–60 seconds
QueryPort conflictQueryPort in Game.ini must be different from the game port. Check Startup in the panel for the assigned value
QueryPort mismatchThe QueryPort= value in Game.ini must match the -QueryPort= startup argument — don't hand-edit one without the other
Port not allocatedXGamingServer allocates the query port automatically. If you reset configs, verify QueryPort matches the value shown in Startup
EOS outageIf every Evrima server is affected, check EOS status or The Isle Discord. Nothing can be fixed server-side

QueuePort can share the same value as QueryPort per the official docs. If the queue isn't needed, set bQueueEnabled=false in Game.ini.

Client Connection Timeout

If players see the following in their client log:

UNetConnection::Tick: Connection TIMED OUT. Closing connection..
Elapsed: 20.01, Threshold: 20.00
CauseFix
Server crashedCheck Console — the server may have gone offline. Restart from the panel
EOS net driver failedRestart the server to reinitialize the EOS connection
Client-side network issuePlayer should verify their connection and ping to the server
Server overloadedCheck CPU and memory in Activity. Lower AIDensity or MaxPlayerCount if saturated

Server Crashes on Startup

Check the Console logs — the error usually appears right before the crash.

CauseFix
Bad Game.ini syntaxTypo or invalid value. Check for missing quotes, wrong section headers ([/Script/TheIsle.TIGameSession]), or invalid types
Missing EOS credentialsAdd the [EpicOnlineServices] block to Engine.ini. See Server Configuration
Corrupted installStop server, delete all files, click Reinstall Server on the Dashboard. See Wipe & Reinstall
Out of memoryLower MaxPlayerCount or AIDensity. See Server Requirements
Port conflictIf RCON port (8888) or Queue port (10000) is in use, change them in Game.ini

Server Starts Then Immediately Stops

This usually means the server initialized but failed during startup. Check the Console for the last few lines.

CauseFix
Invalid MapNameCurrently the only valid value is Gateway
RCON port conflictChange RconPort to a different value
Queue port conflictChange QueuePort to a different value
EOS auth failedEngine.ini credentials are wrong or missing

High Ping or Lag

CheckFix
Server resource usageCheck Activity in the panel. If CPU or RAM is at 100%, the server is overloaded
AI density too highLower AIDensity to 0.5 in Game.ini. Biggest single performance gain
Too many AI checksIncrease AISpawnInterval to 60 or 90
Too many corpsesRun wipecorpses via RCON periodically
Player count exceeds planEither reduce MaxPlayerCount or upgrade your plan

RCON Not Working

CheckFix
bRconEnabled=trueMust be set in Game.ini
Correct portDefault is 8888 (TCP) — verify it's open
Correct passwordThe password is case-sensitive
Using a custom clientStandard Source RCON tools won't work — use a community Evrima RCON client
Restart after editingAlways restart the server after changing RCON settings

See RCON Setup for the full guide.

Whitelist Not Working

CheckFix
bServerWhitelist=trueMust be set under [/Script/TheIsle.TIGameSession]
Steam IDs are correctUse steamid.io to verify SteamID64 format (17 digits)
Restart after editingOr use togglewhitelist via RCON to reload
IDs in the right sectionWhitelistIDs= should be under [/Script/TheIsle.TIGameSession]
