The use of https proxies for requests in python

I found an HTTPS proxy to request, but I could not access it(the access without proxy was successful, and I also tested that the proxy IP was available). Please help me to find out the cause. What's the solution? Thank you very much.

#! /usr/bin/python
# coding=utf-8
import requests
import time
# 请求地址
targetUrl = "https://ip.900cha.com/"

# #代理服务器
proxyHost = "180.113.64.100"
proxyPort = 40055

#非账号密码验证
proxyMeta = "https://%(host)s:%(port)s" % {
    "host": proxyHost,
    "port": proxyPort,
}

proxies = {
    "https": proxyMeta
}

resp = requests.get(targetUrl, proxies=proxies,timeout=10)
print(resp.text)

The error message is as follows:
requests.exceptions.SSLError: HTTPSConnectionPool(host='ip.900cha.com', port=443): Max retries exceeded with url: /(Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol(_ssl.c:1131)')))
