bsc = "https://bsc-dataseed1.defibit.io/" web3 = Web3(Web3.HTTPProvider(bsc))

电脑开代理就程序就报错： requests.exceptions.ProxyError: HTTPSConnectionPool(host='bsc-dataseed1.defibit.io', port=443): Max retries exceeded with url: / (Caused by ProxyError('Cannot connect to proxy.', OSError(0, 'Error')))

这是为什么呢，要如何解决。
