1008 Policy Violation
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.
When You See This Code
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.
How to Fix
Review the server's documented policies and constraints. Check for rate limiting, authentication token expiry, or forbidden message content that triggered the rejection.
