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:
| Check | Fix |
|---|---|
| Server is running | Check Console for errors. Server must show "Server listening" |
| EOS credentials | Verify Engine.ini has the [EpicOnlineServices] section with the right DedicatedServerClientId and DedicatedServerClientSecret. Without these, the server won't register |
| Unique server name | Make sure ServerName is set in Startup or Game.ini |
| Max ping filter | In the player's game Settings > In-Game, set max ping filter to 500–1000 |
| Players on Evrima branch | All 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.
| Cause | Fix |
|---|---|
| Server just restarted | Wait 1–2 minutes after the map finishes loading — EOS session registration takes 30–60 seconds |
| QueryPort conflict | QueryPort in Game.ini must be different from the game port. Check Startup in the panel for the assigned value |
| QueryPort mismatch | The QueryPort= value in Game.ini must match the -QueryPort= startup argument — don't hand-edit one without the other |
| Port not allocated | XGamingServer allocates the query port automatically. If you reset configs, verify QueryPort matches the value shown in Startup |
| EOS outage | If every Evrima server is affected, check EOS status or The Isle Discord. Nothing can be fixed server-side |
QueuePortcan share the same value asQueryPortper the official docs. If the queue isn't needed, setbQueueEnabled=falseinGame.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| Cause | Fix |
|---|---|
| Server crashed | Check Console — the server may have gone offline. Restart from the panel |
| EOS net driver failed | Restart the server to reinitialize the EOS connection |
| Client-side network issue | Player should verify their connection and ping to the server |
| Server overloaded | Check 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.
| Cause | Fix |
|---|---|
| Bad Game.ini syntax | Typo or invalid value. Check for missing quotes, wrong section headers ([/Script/TheIsle.TIGameSession]), or invalid types |
| Missing EOS credentials | Add the [EpicOnlineServices] block to Engine.ini. See Server Configuration |
| Corrupted install | Stop server, delete all files, click Reinstall Server on the Dashboard. See Wipe & Reinstall |
| Out of memory | Lower MaxPlayerCount or AIDensity. See Server Requirements |
| Port conflict | If 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.
| Cause | Fix |
|---|---|
Invalid MapName | Currently the only valid value is Gateway |
| RCON port conflict | Change RconPort to a different value |
| Queue port conflict | Change QueuePort to a different value |
| EOS auth failed | Engine.ini credentials are wrong or missing |
High Ping or Lag
| Check | Fix |
|---|---|
| Server resource usage | Check Activity in the panel. If CPU or RAM is at 100%, the server is overloaded |
| AI density too high | Lower AIDensity to 0.5 in Game.ini. Biggest single performance gain |
| Too many AI checks | Increase AISpawnInterval to 60 or 90 |
| Too many corpses | Run wipecorpses via RCON periodically |
| Player count exceeds plan | Either reduce MaxPlayerCount or upgrade your plan |
RCON Not Working
| Check | Fix |
|---|---|
bRconEnabled=true | Must be set in Game.ini |
| Correct port | Default is 8888 (TCP) — verify it's open |
| Correct password | The password is case-sensitive |
| Using a custom client | Standard Source RCON tools won't work — use a community Evrima RCON client |
| Restart after editing | Always restart the server after changing RCON settings |
See RCON Setup for the full guide.
Whitelist Not Working
| Check | Fix |
|---|---|
bServerWhitelist=true | Must be set under [/Script/TheIsle.TIGameSession] |
| Steam IDs are correct | Use steamid.io to verify SteamID64 format (17 digits) |
| Restart after editing | Or use togglewhitelist via RCON to reload |
| IDs in the right section | WhitelistIDs= should be under [/Script/TheIsle.TIGameSession] |
