我在获取历史k线时报错
代码如下，循环所有币种，获取历史k线
for symbol in all_symbol:
um_futures_client = UMFutures()
res_kline = um_futures_client.klines(symbol, "1d", limit=240)
换成下边这个接口也是一样的
ret_kline =um_futures_client.continuous_klines(“BTCUSDT”, “PERPETUAL”, “1d”)
报错如下
urllib3.exceptions.SSLError: TLS/SSL connection has been closed (EOF) (_ssl.c:997)
The above exception was the direct cause of the following exception:

During handling of the above exception, another exception occurred:
- 这种问题一般是什么造成的，我在两次调用之间也加了sleep 100ms。
- 我的apikey没有指定ip，这里必须固定ip吗？
- 我是通过vpn连的，请问有影响吗
