WebSocket
1006 Abnormal Closure
A reserved value indicating the connection was closed abnormally without a Close frame being sent. This code must not be set by an endpoint.
เมื่อคุณพบรหัสนี้
The TCP connection dropped unexpectedly — the server crashed, the network cable was unplugged, or a firewall killed the idle connection. No proper WebSocket Close handshake occurred.
วิธีแก้ไข
Implement reconnection with exponential backoff. Use WebSocket ping/pong frames to detect dead connections early. Check for network-level timeouts or aggressive load balancer idle limits.
