WebSocket 1008 Policy Violation vs 1013 Try Again Later
Both WebSocket 1008 (Policy Violation) and 1013 (Try Again Later) belong to the WebSocket Close Codes category. 1008 indicates 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. 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.
描述
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.
何时出现
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.
如何修复
Review the server's documented policies and constraints. Check for rate limiting, authentication token expiry, or forbidden message content that triggered the rejection.
描述
The server is terminating the connection due to a temporary condition, such as being overloaded. The client should reconnect after a back-off period.
何时出现
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.
如何修复
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.
主要区别
WebSocket 1008: 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.
WebSocket 1013: The server is terminating the connection due to a temporary condition, such as being overloaded. The client should reconnect after a back-off period.
You encounter 1008 when 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.
