    I run my Telegram BOTs on Heroku and normally start the webhook then is set it:

    updater.start_webhook(listen="0.0.0.0",
                      port=int(os.environ.get("PORT", 5000)),
                      url_path='token'
updater.bot.setWebhook("https://myapp.com/token")

updater.idle()

    When deploying on Heroku you get a URL for your application using SSL (https://myapp.herokuapp.com), which you then configure via the BotFather.

    Providing the BotFather with a HTTPS url is a must, I wonder if you don’t do that or maybe there is an issue with the SSL certificate you are using (self-signed?)

    The problem is that the default port in App Engine is 8080
    And the webhook in telegram does not support this port (just ports 443, 80, 88, or 8443)
