WebSocket 1001 Going Away vs 1013 Try Again Later
Both WebSocket 1001 (Going Away) and 1013 (Try Again Later) belong to the WebSocket Close Codes category. 1001 indicates that an endpoint is going away, such as a server shutting down or a browser navigating away from the page. The connection must be closed. Meanwhile, 1013 means that the server is terminating the connection due to a temporary condition, such as being overloaded. The client should reconnect after a back-off period.
Descripción
An endpoint is going away, such as a server shutting down or a browser navigating away from the page. The connection must be closed.
Cuándo lo verás
The server is shutting down for maintenance, or the user navigated away from the page or closed the browser tab while a WebSocket was open.
Cómo solucionarlo
Implement automatic reconnection logic with exponential backoff in your client. If the server is restarting, the client should retry after a short delay.

Cuándo lo verás
The server is temporarily overloaded or throttling connections. Unlike 1012, this does not indicate a restart — the server is running but cannot serve more clients right now.
Cómo solucionarlo
Reconnect using exponential backoff (start at 1 second, double each attempt). If persistent, investigate server capacity, scale horizontally, or reduce the number of concurrent connections.
