How do I reduce disconnects in my online game?

Fix your side and handle the rest gracefully: fix server crashes and overload that drop connections, tune your netcode to tolerate unstable connections rather than disconnecting too aggressively, and implement reconnection so a brief network drop doesn't end the player's session. For unavoidable player-side network problems, graceful handling (a reconnect flow) minimizes the impact. Capturing server-side errors and network issues helps you find the disconnect causes on your side, so you fix what's within your control.

What Causes Disconnects in Online Games?

Q: Are disconnects always my game's fault?

No. Some disconnects are unavoidable player-side network problems, their connection dropped, switched networks, or is unreliable, which you can't fix but can handle gracefully with reconnection. Others are your side: server crashes, overload, or netcode that disconnects too aggressively, which you can and should fix. Telling them apart (by whether disconnects concentrate around server problems or spread across players) tells you where to focus, on fixing your side versus handling player-side drops gracefully.

Quick answer: Disconnects come from the connection between player and server breaking: network instability and packet loss on the player's side, server problems (crashes, overload, timeouts), and netcode issues handling unstable connections.

Disconnects, where players get kicked from online play, frustrate players and disrupt sessions. They come from the connection breaking, for reasons on either side. Here's what causes disconnects in online games.

Why Connections Drop

A disconnect means the connection between the player and your server broke, which can happen on either side or in between.

Player-side network instability, the player's connection dropping, switching networks, or being unreliable
Packet loss and timeouts, too much loss or a connection going quiet, triggering a timeout disconnect
Server problems, the server crashing, overloading, or restarting, dropping connections
Server timeouts, the server dropping a client it thinks is unresponsive
Netcode issues, poor handling of unstable connections, disconnecting too aggressively
Infrastructure issues, networking problems between the player and server

Some disconnects are player-side (their network), some are server-side (crashes, overload), and some are netcode handling, the distinction matters for what you can fix.

Distinguishing Player-Side From Your Side

Some disconnects are unavoidable player-side network problems (their connection dropped), which you can't fix but can handle gracefully (reconnection). Others are your fault, server crashes, overload, or netcode that disconnects too aggressively, which you can and should fix. Telling them apart tells you where to focus.

Bugnet captures errors and context from real sessions, including network and server-side issues, so you can see whether disconnects concentrate around server problems (your side) or are spread across players (more likely their side). The pattern helps distinguish the causes.

Reducing Disconnects

Reducing disconnects means fixing your side and handling the rest gracefully: fix server crashes and overload, tune netcode to tolerate unstable connections (not disconnect too aggressively), and implement reconnection so a brief drop doesn't end the session. For unavoidable player-side drops, graceful handling minimizes the impact.

Bugnet captures server-side errors and network issues, helping you find the disconnect causes on your side. So disconnects come from player-side network instability and server or netcode problems, and reducing them means fixing server issues, tuning netcode, and handling drops gracefully with reconnection.

Disconnects come from player-side network instability and server or netcode problems (crashes, overload, aggressive timeouts). Fix your side (server, netcode), handle player-side drops gracefully with reconnection.
