• 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.

• 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.

Über diese Anleitungen

Gameserver sagen dir meistens, was nicht stimmt, aber in den Worten dessen, was gerade abgestürzt ist: ein Java-Stacktrace, eine Steam-Auth-Meldung, eine Zeile in einer Logdatei. Die Anleitungen hier sind nach der Meldung geordnet, die du sehen kannst, damit du nach dem Text auf deinem Bildschirm suchen und die Ursache finden kannst statt einer Liste von Dingen, die man probieren könnte.

Jede davon erklärt, was der Fehler wirklich bedeutet, von welcher Seite er kommt (dein Server, deine eigene Verbindung oder die Dienste des Spiels) und wie du ihn am schnellsten loswirst. Wenn deine Meldung nicht dabei ist, zeigt dir die Log-Anleitung in den Hosting-Grundlagen, wie du den echten Fehler hinter einer allgemeinen Meldung findest, und unser Team liest ein Log auch gern mit dir im Discord durch.
