can't connect by using proxy

[StanislavTomilov]

Hello, I have tried to connect by using proxy:

client = TelegramClient('anon', api_id, api_hash, proxy=(socks.SOCKS5, '138.68.165.154', 1080))

async def main():
    # Getting information about yourself
    me = await client.get_me()

    # "me" is an User object. You can pretty-print
    # any Telegram object with the "stringify" method:
    print(me.stringify())

with client:
    client.loop.run_until_complete(main())

got this result: Traceback (most recent call last): File "C:/Users/Xiaomi/PycharmProjects/TelegramTrader/TTApp/Tests.py", line 28, in with client: File "C:\Users\Xiaomi\PycharmProjects\TelegramTrader\venv\lib\site-packages\telethon\helpers.py", line 122, in _sync_enter return loop.run_until_complete(self.aenter()) File "C:\Users\Xiaomi\AppData\Local\Programs\Python\Python37\lib\asyncio\base_events.py", line 584, in run_until_complete return future.result() File "C:\Users\Xiaomi\PycharmProjects\TelegramTrader\venv\lib\site-packages\telethon\client\auth.py", line 635, in aenter return await self.start() File "C:\Users\Xiaomi\PycharmProjects\TelegramTrader\venv\lib\site-packages\telethon\client\auth.py", line 139, in _start await self.connect() File "C:\Users\Xiaomi\PycharmProjects\TelegramTrader\venv\lib\site-packages\telethon\client\telegrambaseclient.py", line 414, in connect proxy=self._proxy File "C:\Users\Xiaomi\PycharmProjects\TelegramTrader\venv\lib\site-packages\telethon\network\mtprotosender.py", line 124, in connect await self._connect() File "C:\Users\Xiaomi\PycharmProjects\TelegramTrader\venv\lib\site-packages\telethon\network\mtprotosender.py", line 211, in _connect raise ConnectionError('Connection to Telegram failed %d time(s)', attempt) ConnectionError: [Errno Connection to Telegram failed %d time(s)] 6

checked proxy, it works:

resp = requests.get('https://www.google.com/', proxies=dict(http='http://138.68.173.29:1080'))
print(resp)

what i'm doing wrong?

Proxy type

socks5, I've tried socks4 (same error) and http(didn't get an answer) too

Maybe the problem cased by zero timeout in socket. See this PR for details
