Aryan SinghandClaude Fable 5 279d137ce5 Minecraft 26.2 Fabric server stack with CraftDeck management panel

- docker-compose: itzg/minecraft-server (Fabric, offline mode, whitelist
  enforced, Modrinth-managed mods), itzg/mc-backup sidecar, custom dashboard
- Gated auth for offline mode: approve username -> whitelisted with a short
  registration window -> EasyAuth /register + /login; auto-revoke on expiry
- CraftDeck panel (Next.js 16, zero native deps): live console (SSE), players
  & stats, lag diagnostics (server TPS vs player ping via spark), performance
  graphs, Modrinth mod search/manager, backups & restore, sandboxed file
  browser/editor, .env config editor with compose apply, cron schedules,
  Discord alerts, scrypt-hashed panel login
- scripts/setup.sh generates secrets; docs/ covers auth, mods, updating,
  backups, networking (Tailscale), troubleshooting

Troubleshooting

Server won't start

Check the Console page first (or docker logs mc --tail 100).

Symptom in logs	Fix
`EULA` complaints	`EULA=TRUE` is set by compose — make sure you didn't override it
A mod failed to resolve for your version	Remove that slug on the Mods page, Apply. (New MC version + mod hasn't updated yet.)
`OutOfMemoryError`	Lower `MC_VIEW_DISTANCE`, or raise `MC_MEMORY`/`MC_CONTAINER_MEM_LIMIT` if the host has headroom
Port already in use	Something else on 25565 — change `MC_PORT` in `.env`
Crash right after "Done"	A mod conflict — disable recently added jars (Mods page → power icon)

A friend can't join

Work down this list:

"Not whitelisted" → their username isn't approved (or the window expired and auto-revoked them). Access & Auth → approve/re-open. Username must match exactly (case matters in TLauncher).
Joins but immediately kicked → they didn't /register or /login in time — EasyAuth kicks unauthenticated players after a timeout. Tell them to type faster or raise the timeout in config/EasyAuth/.
"Connection timed out" → networking: is 25565 port-forwarded? Are they using your public IP? Does docker compose ps show mc healthy?
Wrong password loop → Access & Auth → Reset password, share the temporary one privately.

Panel shows "Offline" but the server is up

The dashboard container can't reach the Docker socket or RCON:

docker compose ps                      # is mc-dashboard running?
docker logs mc-dashboard --tail 50
docker compose up -d --force-recreate dashboard

If you changed RCON_PASSWORD in .env, Apply/recreate both mc and dashboard so they agree.

Forgot the panel password

docker compose stop dashboard
rm data/dashboard/craftdeck.db        # wipes panel users/settings/history — NOT the world
# set PANEL_ADMIN_PASSWORD in .env to a fresh value
docker compose up -d dashboard

Player approvals are re-importable afterwards (Access & Auth → Import whitelist).

Lag

Performance & Lag page tells you who is lagging (server vs a player's connection). If it's the server: check the CPU/memory charts, run the spark health report, lower view/simulation distance, or add more RAM. If it's one player: it's their network — nothing to fix server-side.

Disk filling up

Backups page shows total backup size; lower BACKUP_RETENTION_DAYS. The panel also raises a low-disk alert below 2 GB free.

Nuke everything and start over (keeps nothing)

docker compose down
rm -rf data
./scripts/setup.sh && docker compose up -d
