Frequently asked

What file should I paste into the Crash Doctor?

Minecraft writes a crash-report.txt to the crash-reports/ folder every time the server hard-crashes. Paste that whole file. If the server didn't write one but just stopped, paste the last 200–500 lines of logs/latest.log instead.

Do you store my crash report?

Only if you click 'Share this diagnosis'. Even then we strip secrets, passwords, Discord webhooks and IP addresses before saving. Shared diagnoses auto-expire after 30 days.

Why does it say 'no crash pattern detected'?

Either the server shut down cleanly, the actual crash report is in a different file, or the log fragment you pasted doesn't include the cause line. Minecraft always writes a separate crash-report.txt — paste that instead of latest.log when possible.
