Too Many Requests error when start_polling()

Hi when I add start_polling() to end of my telegram bot code, telegram API returns too many requests . Bot Support said: this kind of "Too Many Requests" are usually it is caused because you call setWebhook too often. please help me fix this problem.

Hi there, I'm not sure this is a PythonAnywhere-specific issue. Hopefully telegram support will be able to help further?
