WebSocket 1012 Service Restart vs 1013 Try Again Later
Both WebSocket 1012 (Service Restart) and 1013 (Try Again Later) belong to the WebSocket Close Codes category. 1012 indicates that the server is terminating the connection because it is restarting. The client should reconnect after a brief delay. 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.

Gördüğünüzde
The server is performing a planned restart — for example, during a deployment or configuration reload. The connection will be available again shortly.

Gördüğünüzde
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.
Nasıl Düzeltilir
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.
