Good evening! Wrote a bot for the telegram on the python. In the process of testing, it was discovered that after a short working time, he ceases to receive updates. And the point here is not in my code, but in the telegram api itself, since a simple opening https://api.telegram.org/bot_token/getUpdates in the browser returns json with OLD messages. Those. a bot account behaves as if I am not writing anything to it. At the same time sending messages through the bot works. About a day later, the update is resumed.
Now I have started several bot accounts and when one is disconnected, I simply change TOKEN to another and work through another account, but this is not an option. I do not understand why this is happening and who to contact.
