# I can't connect to CubeCraft

## "Outdated client" or "Outdated server"

Your game version is not one we support. See [Which version do I need, and how do I update? xxx]

"Outdated **server**" usually means you updated before we did. That gap is normally a few days after a major Minecraft release.

## "You are blocked" with a code starting with C or V

This is a connection block, not a ban on your account. See [Why is my connection blocked?] for what it means and how long it lasts.

||| It is automatic, it cannot be appealed, and nobody on the team can shorten or lift it. 

## "Not Authenticated with Minecraft.net" (Java)

1. Fully close and reopen the Minecraft Launcher.
2. Sign out of your Microsoft account in the launcher, then sign back in.
3. Try again.

||| If you use a cracked or offline launcher, including TLauncher, you will always get this error. CubeCraft requires a legitimate account and there is no workaround.

If you own the game and the error persists after a restart, the problem is with Minecraft's authentication rather than with us. Contact [Minecraft support](https://aka.ms/Minecraft-Support).

## "Invalid session" (Java)

Restart the game. This generates a new token/key allowing you to access Minecraft's multiplayer services. If restarting does not work, sign out of your account and back in.

| If you also see "Authentication servers are under maintenance", Mojang's login service is down. Nobody can connect to any server until it returns.

## "An error occurred obtaining your user ID"

This is currently a known bug across our network. Our development team are working on a fix, however in the meantime we recommend to restart your Minecraft client as this helps to resolve the issue.

## "Server is down for maintenance"

Nobody can join during maintenance. It is announced on our [Discord](https://discord.gg/cubecraft) and [Instagram account](https://www.instagram.com/cubecraftgames/). Try again later.

## My game fully crashes

This is a known issue caused by Microsoft. See [their bugs board](https://bugs.mojang.com/browse/MCPE/issues/MCPE-239705) for more information.
## It times out, or I lag badly

1. Restart your router.
2. Turn off any VPN.
3. Disconnect other devices using the connection heavily.
4. If it continues, run a netcheck and send us the result. See [Run a netcheck xxx].

## Still stuck?

Send us an email at support@cubecraft.net with all five of these:

* your username,
* your platform,
* your exact game version,
* the exact wording of the error (or a screenshot),
* what you already tried.

|| Almost every "can you send more details?" reply from us is asking for one of those five. Including them all up front usually saves a day.
