The Isle Evrima Server Troubleshooting Guide

This guide helps you fix the most common issues that players and server owners experience with The Isle Evrima — connection problems, lag, crashes, RCON trouble, and game-update or gameplay glitches.

Connection Issues

Server Not Showing Up in the Browser

Evrima does not support direct IP connection — all servers are found via the Epic Online Services (EOS) server browser. If your server isn't appearing:

1. Give it a few minutes — After a start or restart, it can take a good 2–5 minutes for your server to register with the browser. That's normal. If it's been longer, keep going through the list.
2. Make sure the server is running — Log in to the NolimitHost Game Panel, select your server, and check its status. If it says stopped or crashed, restart it.
3. Check your query/ports — Your ports come pre-configured, but if you've changed anything, double-check in the panel (under Network) for the correct port assignments.
4. Avoid special characters in the name — Special characters in your server name can sometimes cause problems. Try simplifying it to basic letters and numbers.
5. Version mismatch — The game client auto-updates through Steam, but your server might still be on the old version. In the panel, trigger a Steam Update (see How to Update Your Server).
6. Look for the exact name — Search for your exact server name. To check it, open Startup in the left sidebar and copy the Server Name.
7. Refresh the browser — Switch the Session Filter between Unofficial and Official, or click the Refresh button.
8. EOS outage? — If the issue persists, EOS may be having an outage. Monitor the Official Isle Discord for announcements.

Players Get Connection Timeouts

They can see the server but can't actually join. Check these:

• Full server — Check your current player count via the panel.
• Password issues — If you've set a server password, remember it's case-sensitive. Double-check players are typing it exactly right.
• Wrong branch — This catches people out constantly. Players must be on the Evrima branch, not Legacy. They switch this in Steam (right-click The Isle → Properties → Betas tab → select Evrima). See How to Enable the Evrima Branch.
• Server under heavy load — If your RAM and CPU are maxed out, the server starts rejecting connections. Check resource usage in the panel and consider upgrading if you're consistently near the limit.
• Port configuration — Check the panel for your specific ports. Don't assume defaults.

Random Disconnections

Players connect fine but get booted during gameplay. The usual suspects:

• Low RAM is the number one cause — The Isle Evrima is a memory hog, especially with lots of players and AI. If your RAM usage regularly exceeds 80%, you need more.
• Scheduled restarts — Check whether you have scheduled restarts configured that you forgot about. If everyone disconnects at the same time every day, that's probably it.
• Corrupted save data — This can cause instability. Restore a recent backup, and after any game update make sure you've updated the server as well — version mismatches cause all sorts of weird behaviour.

Performance Problems

Lag and Rubber-Banding

This is probably the most common complaint. Here's what to check, roughly in order of likelihood:

1. Monitor your resources — RAM is usually the bottleneck. If you're running more than ~100 players or high AI density, consider adding more RAM or upgrading your plan.
2. Lower AI density — AI eats resources. Lower the AIDensity setting, or use the RCON command aidensity to adjust it on the fly during peak hours.
3. Clean up corpses — Dead dinosaurs sitting around consume server resources. Use wipecorpses via RCON to clean them up, or lower the corpse decay setting so they despawn faster.
4. Restart regularly — The server process leaks memory over time; restarting every 6–12 hours keeps things stable. You can schedule this through the panel.
5. Temporarily lower the max player count — If nothing else helps, reducing it lowers load while you sort things out.

High RAM Usage or Crashes

If you're consistently above 80% RAM or getting out-of-memory crashes:

• Reduce AI density — Dropping AIDensity from 1.0 to 0.5 makes a noticeable difference.
• Lower unused player slots — Reducing the max player count means less memory pre-allocated.
• Restart more often — Every 6 hours instead of every 12.
• Upgrade your RAM — Through the NolimitHost panel or by purchasing a larger plan.

Server Crashes with No Warning

1. Check your logs first — Open the Log Viewer in the panel sidebar and look for error messages near the end; they usually tell you exactly what went wrong.
2. Running out of RAM — Most crashes come down to this. Check your usage trends.
3. Bad entry in Game.ini — If you recently changed settings, a bad entry can crash the server on startup or mid-game. Revert your changes, then restart.
4. After a game update — Some config options get renamed or removed. Reset to defaults and re-apply your customisations one at a time so you can isolate which one causes problems.
5. Still crashing? — Contact our support team with your crash logs.

RCON Troubles

Can't Connect to RCON

The Isle Evrima uses its own RCON protocol — standard tools like mcrcon won't work. Check the basics:

• Use an Evrima-compatible client (TheIsleEvrimaRCON) or our free RCON Tester.
• Make sure you're using the correct RCON port (check the panel for the specific port assigned to your server).
• Your RCON password is entered exactly right (it's case-sensitive).
• The server has fully started before you try connecting — RCON only comes online after the server finishes initialising.

Commands Not Working

• Syntax matters — Evrima RCON commands are case-sensitive. Verified commands include kick [SteamID64,Reason], ban [Name,SteamID64,Reason,Time], playerlist, aidensity, wipecorpses, toggleai, announce [message], and save.
• Commands change between updates — After a game update, some commands get renamed or removed. Check if anything's changed.
• Permissions — Make sure your admin password grants full access.

See the full command reference and setup steps in the How to Use RCON guide.

Frozen Time of Day

If the in-game time appears stuck and never changes, this is almost always caused by non-default ServerDayLengthMinutes or ServerNightLengthMinutes values in your Game.ini file — the main configuration file for your server.

1. Log in to the NolimitHost Game Panel and select your server.
2. Stop your server first — this is important so the server doesn't overwrite your changes when it shuts down.
3. In the left sidebar, click File Manager and navigate to /TheIsle/Saved/Config/LinuxServer/Game.ini.
4. Find the day/night settings and reset them to the defaults:

5. Save the file.
6. Go back to the Console tab and start your server to apply the changes.

Game Update Issues

Version Mismatch After an Update

Steam updated the game client but your server is still on the old version, so players can't connect. In the panel, use Steam Update to pull the latest server files, then restart. Always create a backup first — new versions occasionally break things with your existing config.

Settings Got Overwritten

Game updates sometimes reset your Game.ini. If that happens:

• Restore your config from a backup taken before the update.
• Keep a local copy of your configuration files so you can quickly re-apply settings.
• Check the patch notes — updates sometimes rename settings, so your old values might not be valid anymore.

Player-Reported Issues

Stuck on the Spawn Screen

If players can't spawn or select a dinosaur:

• Check your AllowedClasses configuration — If you've restricted the dinosaur roster, make sure at least some species are actually available. An empty or broken AllowedClasses list blocks spawning entirely.
• Corrupted save — Try restarting, or restore from a backup if it persists.
• Player-side — Have them verify game files through Steam (right-click The Isle → Properties → Local Files → Verify Integrity).

Growth Not Progressing

Players say their dinosaurs aren't growing even though they're eating and drinking. Before you start tweaking settings, know that Evrima has diet requirements — dinosaurs need to eat the right food types for their species. Eating the wrong thing doesn't count toward growth. That's by design, not a bug.

If it's actually a server-side issue:

• Check that GrowthMultiplier isn't set to 0 or something absurdly low.
• Severe server lag can slow down growth calculations — check performance if this happens alongside other issues.

Game Crashes on Connection

If your game crashes when connecting to or playing on a server:

• Verify your game files through Steam: right-click The Isle → Properties → Installed Files → Verify integrity of game files.
• Ensure your GPU drivers are up to date — or roll back to a previous driver version if crashes started after a recent driver update.
• Check the Official Isle Discord to see if other players are reporting the same issue.
• Copy the exact error message or code and search Steam, Reddit, or the Isle forums for similar reports.
