Cannot get NEXT_QUARTER price via websocket stream

As I found in document (https://binance-docs.github.io/apidocs/delivery/cn/#b14c7e3649) that I can subscribe next quarter by using wss://stream.binance.com:9443/ws/adausd_210924@aggTrade. But it doesn’t work for me.

Sending SUBSCRIBE method manually returns {\"result\":null,\"id\":1} while the other streams like btcusdt@aggTrade works for me.

Did I do something wrong? How count I get fix this? Thanks~

Hi. You have to change your base from stream to dstream as your subscription target belongs to futures market. That is, wss://dstream.binance.com/ws/adausd_210924@aggTrade

Thank you~
