Many thanks
5-second heartbeat didn't fix it either. The pattern is clear now — it's not a heartbeat timing issue. The 499 is a server-side close from WhatsApp/WebSocket, happening every 60 seconds on the dot.
This is almost certainly a network infrastructure issue on Zeabur's side — their load balancer or firewall is cutting connections at exactly 60 seconds of inactivity, regardless of how aggressively the client sends heartbeats.
The honest situation: We've exhausted what the heartbeat setting can do. Options to actually fix this:
- Switch hosting — move to a provider without a 60-second idle timeout (or one that allows WebSocket connections to stay open longer)
- Use a VPN/tunnel — route the gateway's WhatsApp traffic through something that doesn't have this timeout
- WhatsApp Business API — a more proper integration that doesn't rely on WhatsApp Web's WebSocket
I know none of those are ideal. The reconnect loop is annoying but the gateway does recover instantly each time — messages still go through between disconnects. It's not ideal but it's working.
What would you like to do?
