"Outdated client! Please use 1.21.x"

Why

The player's Minecraft version is older than the server's.

Fix

1. In the launcher, pick "Latest release" (or 1.21.4+) and hit Play.
2. Using a modpack or Lunar/Badlion? Switch that profile to 1.21.4.

"Connection timed out: no further information"

Why

The player can't reach the server at all. Usually a typo in the IP, their network, or the server is restarting.

Fix

1. Check the IP is exactly play.caelumsmp.com (no https://, no port).
2. Check #status on Discord for a restart or outage.
3. Ask them to try a phone hotspot. If that works, it's their network or firewall.
4. School and work networks often block Minecraft. Nothing we can do there.

Escalate: More than 3 players reporting it at once: ping an Admin, the server may be down.

"Failed to verify username!"

Why

Mojang's login servers couldn't confirm the account. Usually a stale launcher session.

Fix

1. Fully restart the launcher (log out and back in if that doesn't help).
2. Check status.mojang.com. If Mojang is down, everyone has to wait it out.
3. Cracked or offline-mode accounts can't join. We're a premium-only server.

"You don't have Pebble's permission to build here."

Why

They're inside someone else's claim. Claims are working as intended.

Fix

1. Show them the claim edges: hold a golden shovel or run /claim show.
2. If it's their friend's claim, the owner runs /trust <player>.
3. If they say the claim is theirs, check /claim info. Alts and name changes sometimes cause this.

"My items disappeared after a lag spike"

Why

A rollback or crash lost their last few seconds, or they died and didn't notice.

Fix

1. Run /co lookup u:<player> a:inventory t:1h to see what they had.
2. Check /deaths <player> for a recent death.
3. If the log shows the items, escalate to a Mod for a restore. Helpers can't give items.

Escalate: Item restores are Mod-only. Paste the lookup output in the ticket.
