WebSocket
1000 Normal Closure
The connection has been closed cleanly, meaning the purpose for which it was established has been fulfilled. Both endpoints agree the session is complete.
이 코드를 보게 되는 경우
The WebSocket connection closed gracefully after both sides finished exchanging data. This is the expected close code for a successful session.
해결 방법
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.
