• Fix Palworld "Failed to join session" and connection errors

  Palworld gives you two ways to join a server and almost all join failures come from using the wrong one for your platform. Here is which is which.

• Fix Rust "Disconnected: Steam Auth Timeout"

  Steam's authentication service did not answer in time, so the server could not confirm who you are. This is almost never the server, and waiting really is sometimes the fix.

• Your server stops seconds after starting: reading exit codes

  A server that dies within seconds has already told you why. The exit code narrows it down and the five lines above it name the cause.

• Fix "Exception ticking world" and corrupted chunks

  One mob, block or chunk in your world errors every time the server touches it. The crash report gives you its coordinates, and a backup is almost always the cleanest fix.

• Fix "Mod rejections" and modded version mismatches

  Forge, NeoForge and Fabric compare mod lists at the door and refuse a player whose list does not match. The rejection screen names the mods, which is more help than it looks.

• Fix io.netty.channel.AbstractChannel$AnnotatedConnectException

• Fix "Address already in use" on a game server

  Two things want the same port and only one can have it. The usual causes are an old process that has not finished dying and a plugin quietly claiming a port of its own.

• Fix "A single server tick took 60.00 seconds" (watchdog crash)

• Fix "You need to agree to the EULA" on a Minecraft server

• Fix "java.lang.OutOfMemoryError: Java heap space"

• Fix "Internal Exception: java.io.IOException" in Minecraft

  This error means the connection between a player's client and your Minecraft server broke mid-message. Here is how to tell a bad home connection from a plugin, a proxy or a restart.

À propos de ces guides

Les serveurs de jeu ont tendance à te dire ce qui cloche, mais dans les mots de ce qui a planté : une stack trace Java, un message d'authentification Steam, une ligne dans un fichier de log. Les guides ici sont rangés par message visible, pour que tu puisses chercher le texte affiché à l'écran et obtenir la cause plutôt qu'une liste de choses à essayer.

Chacun explique ce que l'erreur veut vraiment dire, de quel côté elle vient (ton serveur, ta propre connexion, ou les services du jeu), et le chemin le plus court pour la faire disparaître. Si ton message n'est pas là, le guide sur les logs dans Bases de l'hébergement te montre comment retrouver la vraie erreur derrière une erreur générique, et notre équipe lira un log avec toi sur Discord.
