Real-Time Features Not Working (Chat, Notifications, Live Updates)
Your app has real-time features (chat, live notifications, real-time data updates) but they don't work. Messages don't appear until you refresh, notifications are delayed or missing, or the live update feature requires manual refreshing.
Common Causes
- WebSocket connection failing or not supported by the hosting platform
- Real-time subscriptions not set up correctly in the database
- The app uses polling but the interval is too long or the polling broke
- Hosting platform doesn't support persistent connections (serverless limitation)
- Supabase Realtime not enabled for the relevant tables
How to Fix It
- Check the browser console for WebSocket connection errors
- If using Supabase, verify that Realtime is enabled for the tables you need
- Check if your hosting platform supports WebSockets (some serverless platforms don't)
- Verify the real-time subscription code is listening to the correct channel/table
- As a fallback, implement polling (periodic refresh) until WebSockets are fixed
Real developers can help you.

Get HelpFrequently Asked Questions
Chat messages only appear after I refresh the page. Why?
The real-time subscription is probably not working. This could be a WebSocket connection issue, incorrect subscription setup, or a hosting platform limitation.
Can real-time features work on any hosting platform?
Not all platforms support WebSockets. Serverless platforms often can't maintain persistent connections. A developer can recommend the right setup for your needs.
