WebSocket Connection Dropping in Lovable App
Your Lovable app uses WebSocket connections for real-time features (chat, notifications, live updates), but the connections keep dropping. Users see messages arrive late, live data stops updating, or the app shows 'disconnected' states frequently.
WebSocket connections are long-lived and sensitive to network changes. Mobile users switching between WiFi and cellular, users on unstable connections, and server-side timeouts all cause disconnections that need to be handled gracefully.
Without proper reconnection logic, a single disconnection means the user's real-time features stop working until they refresh the entire page.
Error Messages You Might See
Common Causes
- No reconnection logic — The app establishes a WebSocket connection once but doesn't reconnect when it drops
- Server-side idle timeout — The server or reverse proxy (Nginx, Cloudflare) closes idle connections after a timeout period
- Network changes — User switches from WiFi to cellular or enters a tunnel, causing connection loss
- Too many connections — Server or plan limits the number of concurrent WebSocket connections
- Missing heartbeat/ping — No keep-alive mechanism to detect dead connections and maintain the connection through proxies
How to Fix It
- Implement automatic reconnection — Use exponential backoff reconnection: wait 1s, then 2s, then 4s, etc., with a maximum delay
- Add heartbeat/ping mechanism — Send periodic ping messages to keep the connection alive and detect dead connections early
- Handle visibility change — When the user switches back to your tab, check the connection and reconnect if needed
- Use Supabase Realtime properly — Supabase handles reconnection automatically if you use their channel API correctly
- Show connection status to users — Display a 'reconnecting...' indicator so users know the app is recovering

Get HelpFrequently Asked Questions
How often do WebSocket connections drop in normal use?
On stable WiFi, connections can last hours or days. On mobile, disconnections are common when switching networks, entering elevators/tunnels, or after phone sleep. Your app should expect and handle disconnections gracefully.
Should I use WebSockets or Supabase Realtime?
Use Supabase Realtime if your data is in Supabase — it handles connection management, reconnection, and authentication automatically. Use raw WebSockets only for custom real-time protocols not tied to database changes.
