Exception occurred while requesting https URL using proxy aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host

[ohblue]

Describe the bug

Error when requesting https site through proxy using ClientSession.get()

To Reproduce

run this demo:

from proxy import Proxy
import requests
import asyncio
import aiohttp

proxy = Proxy()

proxies = proxy.get_proxy()
print(proxies)

# use requests
res = requests.get("https://ifconfig.me/all", proxies=proxies)
print(res.text)

# use aiohttp
async def main():
    url = "https://ifconfig.me/all"
    async with aiohttp.ClientSession(connector=aiohttp.TCPConnector(ssl=False),trust_env=True) as session:
        async with session.get(url,proxy=proxies['http'],ssl=False) as resp:
            text = await resp.text()
            print(text)
asyncio.run(main())

Expected behavior

The normal return when requesting https://ifconfig.me/all is as follows:

ip_addr: *.*.*.*
remote_host: unavailable
user_agent: python-requests/2.31.0
port: 49880
language:
referer:
connection:
keep_alive:
method: GET
encoding: gzip, deflate
mime: */*
charset:
via: 1.1 google
forwarded: *.*.*.*,*.*.*.*

Using the same URLs and proxies, it works fine when requesting with the requests library

ip_addr: *.*.*.*
remote_host: unavailable
user_agent: python-requests/2.31.0
port: 52302
language:
referer:
connection:
keep_alive:
method: GET
encoding: gzip, deflate
mime: */*

forwarded: *.*.*.*,*.*.*.*

Can you try in Python 3.12? It think HTTPS-in-HTTPS is only supported in Python 3.11+, so could be something to do with that.

I tried in python3.12.2, the problem remains the same

I tried using socks5 proxy via aiohttp_socks library and the problem solved.
