WebSocket 1008 Policy Violation vs 1011 Internal Error
Both WebSocket 1008 (Policy Violation) and 1011 (Internal Error) 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, 1011 means that the server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request.
विवरण
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.
जब आप इसे देखें
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.
कैसे ठीक करें
Review the server's documented policies and constraints. Check for rate limiting, authentication token expiry, or forbidden message content that triggered the rejection.
विवरण
The server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request.
जब आप इसे देखें
The server hit an unhandled exception or crashed while processing a WebSocket message. This is the WebSocket equivalent of HTTP 500 Internal Server Error.
कैसे ठीक करें
Check the server-side application logs for stack traces and exceptions. Fix the underlying bug that caused the crash and add proper error handling around message processing.
