`ws://` used in the code report an error under the `https` protocol

[aliuq]

index-DrLOjSgh.js:500 Mixed Content: The page at 'https://xxx.xxx/' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://xxx.xxx/websocket'. This request has been blocked; this endpoint must be available over WSS.

Uncaught SecurityError: Failed to construct 'WebSocket': An insecure WebSocket connection may not be initiated from a page loaded over HTTPS.

Should choose ws or wss based on the protocol?
