Can't connect my chatbot to Telegram

I have a chatbot ready to be integrated to Telegram and I am using ngrok for the webhook url. In credentials.yml i have the following code:

telegram:
  access_token: 190******************:****************************************
  verify: M*******************_BOT
  webhook_url: "https.ngrok.io/webhooks/telegram/webhook"

when I paste the ngrok url in my browser with the Rasa server started it gives me the message “Hello from Rasa 2.8.2” which means that it should work, but when I go and talk to my bot on Telegram it does not reply and it seems that is not integrated. Does anyone know what seems to be the problem? Thanks in advance!

Hi, you can check out the below video of mine: If you still face issue let me know

Hi, after 2 days I realized that the bot works but it doesn´t work for my Telegram account. I have tested it with 3 other accounts and It works perfectly. When I write whatever text it doesn´t respond, but it does work for other Telegram accounts. When I write from my account it gives me these errors and exceptions and I have no idea what the problem could be.
