Telegram bot stops responding after several days of inactivity

I’m having an issue with my Telegram bot that’s really confusing me. Here’s what happens:

When users first type /start, my bot works perfectly and sends messages as expected. But then after a few days pass, the bot just stops sending any messages at all. The weird thing is that if a user sends any message to the bot, it starts working again like nothing happened.

I can’t figure out why this is happening. Is there some kind of timeout or sleep mode that kicks in after a certain period? I’ve looked around but can’t find any documentation about this behavior. Maybe there’s a setting I’m missing in my bot configuration?

For sending messages, I’m using this API endpoint:

https://api.telegram.org/bot{BOT_TOKEN}/sendMessage?chat_id={CHAT_ID}&text={MESSAGE_TEXT}&disable_web_page_preview=true

Has anyone else experienced this kind of problem? Any ideas on what might be causing the bot to go inactive and how to prevent it?

Same thing happened to me on Render and Railway. It’s not the Telegram API - your host is putting the process to sleep. Free tiers all do this. Switch to Railway’s paid plan or grab a DigitalOcean droplet for $5/month. Way more reliable than constantly fighting sleep mode.

This isn’t a Telegram API issue - it’s your hosting. The API doesn’t have timeouts that make bots stop responding after sitting idle.

Your bot’s probably running on a service that puts inactive processes to sleep. Most free hosting does this to save resources. When someone messages you, it wakes the bot back up.

I’ve dealt with this exact problem running bots on different platforms. The fix isn’t just better hosting - you need proper automation that handles monitoring, health checks, and restarts.

What you need is a solid workflow platform that can:

  • Monitor your bot regularly
  • Send keep-alive requests
  • Restart services automatically
  • Handle webhooks better than polling

I’ve set up dozens of Telegram bots this way and never had the sleeping problem again. You need a system actively managing your bot’s lifecycle instead of hoping it stays awake.

Latenode handles all this seamlessly. You can build monitoring workflows, set up health checks, and create automated responses that keep everything running 24/7. No more mysterious downtime.

Check if you’re using webhooks or polling for updates. I had this exact problem when my webhook URL went unreachable after sitting idle. The bot would miss messages until someone manually triggered it again. Most hosting services kill HTTPS connections or change routing after idle periods. Your webhook’s probably timing out on Telegram’s side, making the bot look unresponsive. When someone sends a message, it forces a reconnection that temporarily fixes things. I fixed this by switching to long polling with getUpdates instead of webhooks. Less elegant but way more reliable for bots without constant traffic. You could also set up a simple cron job to ping your webhook every few hours to keep it alive. Your API endpoint looks fine - the problem’s definitely on the receiving end, not sending.

Had the exact same problem and it drove me nuts for weeks. Your server’s going to sleep - it’s not Telegram. The API doesn’t have timeouts that cause this.

Your hosting provider puts your app to sleep when it’s not being used to save resources. Happens all the time with Heroku’s free tier, Railway, and similar platforms. When someone messages you, it wakes the bot back up.

Fix depends on your setup. If you’re on a platform that sleeps apps, either upgrade to a paid plan that keeps things running 24/7, or set up a ping mechanism to keep your bot awake. I switched to a VPS where I control everything and haven’t had the problem since.
