[Python] Proxy works in checker tools but fails in Python (Telethon) with "GeneralProxyError:...

I'm trying to connect to Telegram using Telethon with a SOCKS5 proxy, but I keep getting GeneralProxyError: Socket error: timed out after multiple attempts.

The proxy is verified working in online proxy checkers, but in Python (Telethon), it fails with:

Attempt 1 at connecting failed: GeneralProxyError: Socket error: timed out


CODE:

from telethon.sync import TelegramClient
from telethon.sessions import StringSession
from telethon.network.connection.tcpabridged import ConnectionTcpAbridged
from telethon import functions, types


api_id = 1234
api_hash = '12345'


proxy = {
'proxy_type': 'socks5', # (mandatory)
'addr': '194.32.229.199', # (mandatory)
'port': 1050, # (mandatory)
'username': 'user', # (optional)
'password': 'pass', # (optional)
'rdns': True # (optional)
}


with TelegramClient(
StringSession(), # Сохраняет сессию для повторного входа
api_id,
api_hash,
proxy=proxy,
connection=ConnectionTcpAbridged # Улучшает работу с прокси
) as client:

me = client.get_me()
print(f"Успешная авторизация через прокси!")
print(f"ID: {me.id}")
print(f"Имя: {me.first_name}")
print(f"Username: @{me.username}")

print("\nСтрока сессии для повторного входа:")
print(client.session.save())
