复盘服务无法启动, 由于目标计算机积极拒绝?

是复盘服务已经暂停使用了么?

from tqsdk import TqApi, TqSim, TqBacktest, TqReplay
from contextlib import closing
from datetime import date
 api = TqApi(backtest=TqReplay(date(2020, 6, 10)))
    data = api.get_quote("SHFE.rb2010")
    with closing(api):
        while 1:
            api.wait_update()
