WebSocket protocol violation - invalid frame
Invalid frame header|RSV.*bits must be clear|invalid opcode
Fixes
- 1.Ensure both client and server agree on extensions (permessage-deflate RSV bits)
- 2.Check for intermediary proxies corrupting WebSocket frames — use wss:// to prevent this
- 3.Verify the WebSocket library versions are compatible and not mixing draft/final protocol versions
