Telegram Webhook not responding

[chhofi]

I try to get the telegram node working with the webhook mechanism. For that I set up a Cloudflare Quick Tunnel:

cloudflared tunnel --url http://localhost:1880

When I try to enter the URL in the browser:
https://huntington-florists-sad-conferencing.trycloudflare.com/redbot/telegram/test
I get the response:
ok

also when entering
https://huntington-florists-sad-conferencing.trycloudflare.com/redbot/telegram
I get the response:
{"status":"ok"}

So that should work ...

But in node-red I do not see any incoming message unfortunately ... When I set the mechanism to Pull I can receive the messages.

Can anyone help me to debug this issue?
