What causes the "Server Disconnected" error during raids?

The ''Server Disconnected'' error during raids in Valheim is a common issue that can disrupt gameplay, especially in multiplayer sessions. This error typically occurs due to server instability, high latency, or conflicts between the game''s mechanics and the server''s performance. Raids, which are triggered by in-game events like the appearance of the ''The ground is shaking'' message (indicating a Troll raid), can strain the server due to the sudden increase in enemy spawns and player activity.\n\nOne of the primary causes of this error is server overload. During raids, the game spawns multiple enemies simultaneously, which can overwhelm the server if it lacks sufficient resources or if the connection between players is unstable. For example, if a player is hosting a server on a low-end PC or has a weak internet connection, the server may struggle to handle the increased load, leading to disconnections. This is especially problematic in biomes like the Black Forest or Plains, where raids often involve tougher enemies like Trolls or Fulings.\n\nAnother factor is latency or packet loss. If players are spread across different regions or have inconsistent internet speeds, the server may fail to synchronize all actions during a raid. For instance, if one player is fighting a Troll while another is building defenses, the server might disconnect players to prevent desynchronization. This is more likely to happen in larger multiplayer sessions where multiple players are engaging in combat or construction simultaneously.\n\nTo troubleshoot this issue, start by ensuring that the server host has a stable and high-speed internet connection. If you''re hosting a dedicated server, consider upgrading your hardware or using a third-party hosting service with better performance. For players experiencing frequent disconnections, try reducing the number of active players in the session or limiting activities that strain the server, such as excessive building or farming during raids.\n\nAdditionally, optimize your game settings to reduce strain on the server. Lowering the graphics settings, disabling unnecessary mods, and closing background applications can improve performance. If you''re playing in a biome with frequent raids, like the Plains, consider preemptively building defenses such as stone walls or spike traps to minimize the need for real-time combat, which can reduce server load.\n\nFinally, communicate with your fellow Vikings to coordinate actions during raids. For example, designate specific roles, such as one player focusing on combat while another repairs structures. This can help distribute the server''s workload more evenly and reduce the likelihood of disconnections. By addressing these factors, you can minimize the ''Server Disconnected'' error and enjoy smoother multiplayer raids in Valheim.
