WebSocket 1000 Normal Closure vs 1008 Policy Violation
Both WebSocket 1000 (Normal Closure) and 1008 (Policy Violation) belong to the WebSocket Close Codes category. 1000 indicates that the connection has been closed cleanly, meaning the purpose for which it was established has been fulfilled. Both endpoints agree the session is complete. Meanwhile, 1008 means that an endpoint is terminating the connection because it received a message that violates its policy. This is a generic code when none of the other codes (1003, 1009) are suitable.
Deskripsi
The connection has been closed cleanly, meaning the purpose for which it was established has been fulfilled. Both endpoints agree the session is complete.
Ketika Anda Melihatnya
The WebSocket connection closed gracefully after both sides finished exchanging data. This is the expected close code for a successful session.
Cara Memperbaiki
No fix needed — this indicates everything worked as intended. If you did not expect the connection to close, check your application logic for premature close() calls.

Ketika Anda Melihatnya
The server rejected a message because it violated an application-level policy — for example, sending messages too rapidly, exceeding rate limits, or failing authentication after the handshake.
Cara Memperbaiki
Review the server's documented policies and constraints. Check for rate limiting, authentication token expiry, or forbidden message content that triggered the rejection.
