How to find out from the log why your server crashed
In your Minecraft server folder, open logs/latest.log or the newest file in the crash-reports folder. For a FiveM server or Discord bot, copy the console output.
Paste the end of the log into the field, or upload it with “Upload a file” (.log, .txt or a packed .log.gz).
Leave the type on “Detect automatically”, or choose Minecraft, FiveM or a Discord bot in Node.js or Python.
Click “Analyse” and read the likely cause of the crash, the log lines that show it and how to fix it.
If the tool finds no specific cause, it still shows the root exception and the last error in the log. Start looking there.
About this tool
This crash report analyzer goes through your log and finds the likely cause of the crash.
Paste latest.log, a crash report or a whole console dump (.log.gz works too) and get an explanation of why your Minecraft server crashed, what went wrong on your FiveM server or why your Node.js or Python Discord bot stopped.
Above all, you'll see what to fix: a missing plugin or mod dependency, the wrong Java version, running out of memory, a corrupted world or a script error. The analysis runs only in your browser and the log is never uploaded.

Frequently asked questions
Answers to the questions people ask most about this tool.
Where do I find a Minecraft server log or crash report?
The current log is logs/latest.log in the server folder; older logs are packed as .log.gz. Crash reports are saved in the crash-reports folder. The tool accepts both.
Why does my Minecraft server crash right after starting?
Most often because the EULA hasn't been accepted, the port is already in use, the Java version is wrong, a plugin or mod dependency is missing or a client-only mod is on the server. The tool recognises all of these in the log and tells you what to fix.
Is my log sent anywhere?
No. The analysis runs only in your browser; the log isn't sent to our server or anywhere else, and nothing is stored.
What if the tool can't find the cause?
Then the log doesn't contain a known pattern. Look for the first line with ERROR or Exception before the crash and the plugin, mod or resource named around it. Our common errors guide can help too.
