title: Telegram bot doesn't process messages anymore
body: <p>I face a somewhat weird problem. Unfortunately, I have to diagnose and repair it from distance without any real access. So I don't know if I can provide enough information to solve it.</p>
  <p><strong>Context:</strong>
  I built an interface for my grandma (94) to chat with the family via telegram by connecting a Telegram bot to a microphone (for her to record voice messages) and a small printer (for the messages to be printed for her). [This is inspired by the Yayagram invented!]</p>
  <p><strong>The problem:</strong>
  For the last one year, everything worked just fine. However, a few days ago, the bot stopped working. My grandma could not send any voice messages and didn't receive any of our messages. After calling her and checking all the connections, we restarted the device. Now, she can send voice messages, but the bot still doesn't process our text messages (nor commands!).</p>
  <p>I have never encountered a bot being able to send messages without processing incoming messages. As I said, I have no way to analyze the problem in detail as my grandma lives 500km from me. If anybody has any ideas where the problem could be, I would be very happy.</p>
  <p><strong>Edit:</strong>
  I knew it would work to post a question on StackOverflow! Out of nowhere, the bot seems to work again. I have no idea what caused it, or why it started again as I did nothing. I am still grateful for any insight for what might have caused it!</p>
