"Lost connection to server" — you were in-game and suddenly booted. The server was talking to you and then stopped hearing back. Either your internet blipped, the server crashed, or something ate your bandwidth.
Fix it:
- Check if the game server crashed — if everyone in your match disconnected at the same time, it's the server, not you. Check Discord/Reddit for reports
- Test your internet stability: open Command Prompt, run 'ping -t 8.8.8.8' and watch it for a few minutes. If you see 'Request timed out' or spikes above 200ms, your connection is unstable
- Switch to wired Ethernet if on Wi-Fi — Wi-Fi drops packets under load and gaming is the first thing to suffer
- Stop all downloads and streaming: Windows Update, Steam updates, someone else watching Netflix — any of these can cause momentary disconnects
- Restart your router — a fresh DHCP lease and cleared connection table helps
- Check if your ISP is having issues: search '[your ISP name] outage' or check downdetector.com
- Disable QoS (Quality of Service) on your router if it's misconfigured — bad QoS deprioritizes game traffic
- If it happens at the same time every night, your ISP might have congestion during peak hours. Call them about it
