Telethon bot keeps timing out despite VPN and proxy attempts

Hey everyone, I’m having trouble with my Telethon-based Telegram bot. It keeps timing out no matter what I try. Here’s a simplified version of my code:

from telethon import TelegramClient, events

bot = TelegramClient('my_session', api_id, api_hash)

@bot.on(events.NewMessage(pattern='/hello'))
async def greet(event):
    await bot.send_message(event.chat_id, 'Hello there!')

bot.start()
bot.run_until_disconnected()

When I run this, I get a bunch of timeout errors:

Attempt 1 failed: TimeoutError
Attempt 2 failed: TimeoutError
...
ConnectionError: Connection to Telegram failed 5 times

I’ve tried using a VPS, VPN, and even a proxy, but nothing seems to work. Has anyone else run into this issue? Any ideas on how to fix it? I’m completely stumped!

hey man, i had similar probs with telethon. try checkin ur firewall settings. sometimes they block telegram traffic. also, make sure ur using the right DC (data center) for ur region. u can try manually settin it in ur code. if that dont work, maybe switch to asyncio telethon client. it handles timeouts better in my experience

I’ve encountered similar timeout issues with Telethon, and it can be incredibly frustrating. In my experience, the problem often lies deeper than just network connectivity. Have you checked your API credentials? Sometimes, using outdated or incorrect api_id and api_hash can cause persistent timeouts. Another thing to consider is Telegram’s rate limiting. If you’re making too many requests in a short period, they might be throttling your connection. Try implementing some delay between requests or using exponential backoff for retries. Lastly, I found that upgrading to the latest version of Telethon and its dependencies sometimes resolves these mysterious timeout issues. The library is constantly being improved, and newer versions often include fixes for connection problems. If none of these work, you might want to try alternative libraries like python-telegram-bot or aiogram. They have different connection handling mechanisms that might work better in your specific environment.

Have you considered the possibility of server-side issues? Sometimes, Telegram’s servers can experience temporary hiccups that cause persistent timeouts. In such cases, no amount of client-side tweaking will help. I’d suggest monitoring Telegram’s status page or their official announcements channel for any reported outages. Additionally, try running your bot at different times of the day. If it works fine during off-peak hours but fails during busy periods, it could indicate server overload or regional routing problems. Another often overlooked aspect is DNS resolution. Ensure your system’s DNS settings are correct and try using public DNS servers like Google’s (8.8.8.8) or Cloudflare’s (1.1.1.1). These steps helped me resolve similar issues in the past when all else failed.
