How can I prevent my Telegram bot from disconnecting unexpectedly?

I’m running a Telegram bot using Sidekiq for my app users. It keeps commands coming in but now and then it stops working. I have to restart the Sidekiq worker to get it going again. There’s nothing in the Sidekiq logs that explains why. I’m not sure where to look to fix this.

Here’s a bit of my code for the bot:

class BotWorker
  include Sidekiq::Job
  sidekiq_options queue: :main, retry: 3

  def perform
    puts 'Bot is starting up'
    puts "Config: #{settings.inspect}"

    Bot.start(ENV['BOT_KEY']) do |client|
      client.listen do |msg|
        if msg.sender.handle
          # bot logic here
        end
      end
    end
  end
end

Any ideas on how to keep the bot running without breaks? Thanks for any help!

I’ve faced similar issues with long-running Telegram bots. One effective solution was implementing a heartbeat mechanism. Periodically sending a simple message to check if the bot is responsive can help you identify failures early and trigger a restart when needed.

Another approach is using a process monitor like Monit or systemd to automatically restart the Sidekiq worker if it crashes. Wrapping the bot’s main loop in a begin-rescue block can also catch unexpected errors and provide more insight. Finally, exponential backoff for reconnection attempts may assist in handling network instabilities.

I’ve been running Telegram bots for a while now, and I can tell you that unexpected disconnections can be a real pain. One thing that’s worked wonders for me is implementing a timeout mechanism. Basically, you set a reasonable timeout for each operation, and if it exceeds that, you force a reconnection.

Here’s a rough idea of how you could modify your code:

def perform
  Timeout::timeout(300) do  # 5 minutes timeout
    Bot.start(ENV['BOT_KEY']) do |client|
      client.listen do |msg|
        # Your existing logic here
      end
    end
  end
rescue Timeout::Error
  puts 'Bot timed out, restarting...'
  retry
end

This way, if the bot hangs for any reason, it’ll restart itself after 5 minutes. You might need to tweak the timeout duration based on your specific needs.

Also, don’t forget to log any errors you catch. It’ll help you diagnose issues down the line. Hope this helps!

hey man, i’ve dealt with this before. try using a keep-alive mechanism. send a ping to the telegram api every few mins to keep the connection active. also, wrap ur main loop in a begin-rescue block to catch and log errors. that way u can see whats causing the disconnect. good luck!
