ElectrumX 服务器 jsonRPC 认证

Question

无法连接到 electrum 服务器

错误： HTTPConnectionPool(host='electrum.eff.ro', port=50002): Max retries exceeded with url: / (Caused by NewConnectionError(': Failed to establish a new connection: [WinError 10061] 无法建立连接，因为目标机器主动拒绝'))

连接在 python 中完成：

electrum wallet jsonRPC authentication

import requests
import json


def main():
    url = "http://electrum.eff.ro:50002"
    payload = json.dumps(
        {
            "id": 0,
            "method": "server.version",
            "params": ["1.9.5", "0.6"]
        }
    )
    headers = {'content-type': "application/json", 'cache-control': "no-cache"}

    try:
        response = requests.request("POST", url, data=payload, headers=headers, auth=(rpc_user, rpc_password))
        return json.loads(response.text)
    except requests.exceptions.RequestException as e:
        print(e)
    except:
        print('No response from Wallet, check Bitcoin is running on this machine')


rpc_user = 'foo'
rpc_password = 'bar'

if __name__ == "__main__":
    answer = main()

经常显示这样的错误。

更新：

服务器： url = "http://fortress.qtornado.com:443"

错误：

('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))

如果连接 HTTPS：

url = "https://fortress.qtornado.com:443"

错误：

HTTPSConnectionPool(host='fortress.qtornado.com', port=443): 最大重试次数超过 url: / (由 SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED]证书验证失败：自签名证书 (_ssl.c:1051)')))

如何使用ssl证书连接？
