telegram bot using rasa with the help of ngrok is not working

Question

I'm developing a Telegram bot using rasa and want to use ngrok to receive messages from the webhook.

Setting a webhook works. When I set my publicly reachable domain as URL,and try to run bot on telegram nothing comes out. There is no reply from bot.

when I am trying to run on telegram, nothing comes out and bad gateway error is coming.

ngrok's CLI output:

'''

Answer 1

what is the output on the console? Try running your bot with rasa run --debug and you should get some helpful output that shows what's going wrong. There could be an issue with your credentials
