requests用IP直连时无法用代理怎么办？

Question

代码如下，运行报错404，但是去掉代理proxies参数就可以正常访问了。

proxies = {
    'http': 'http://' + "{}:{}".format(proxy['IP'], proxy['Port']),
    'https': 'https://' + "{}:{}".format(proxy['IP'], proxy['Port']),
}
header = {
    'User-Agent': 'xxxxxxxxx',
    'Host': "www.xxx.com",
}
res = requests.get("http://61.61.61.61:80", headers=header, proxies=proxies)
