vpn代理访问错误

[Hollywood3]

代码如下：proxies={
'http': 'http://127.0.0.1:7897'
}
binanceUM = BinanceUM(
key=key, secret=secret,
proxies=proxies
)
market = binanceUM.market
bookTicker_result = market.get_bookTicker(symbol='BTCUSDT')
eprint(bookTicker_result)
报错如下：
ProxyError: HTTPSConnectionPool(host='fapi.binance.com', port=443): Max retries exceeded with url: /fapi/v1/ticker/bookTicker?symbol=BTCUSDT (Caused by ProxyError('Unable to connect to proxy', SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1129)'))))
我似乎不会设置vpn代理，我用的ccxt的方法，这边显示错误
