Error message

收到未加密数据包

What it means

Raised in mobile_relay_page when a WebSocket packet arrives without the expected AES-GCM encrypted envelope: plaintext or malformed data was received, typically from a key/protocol mismatch between browser and relay or a non-relay client sending frames.

Solutions

1. Confirm both ends use the same access key so encryption modes match
2. Reload the page to renegotiate with the current relay protocol
3. Check no proxy is rewriting WebSocket frames
