No response from telegram bot

Hi. Just added Telegram Bot in control pannel. But no response when I type a message to bot.


  • Used Zammad version: Zammsd 2.2.x
  • Used Zammad installation source: package
  • Operating system: Centos 7 x64
  • Browser + version: Firefox 53.5 x64

Expected behavior:

Bot should send me an invite.

Actual behavior:

Nothing happened.

Steps to reproduce the behavior:

Configure telegram bot in ZAMMAD

I did it.
The problem is with a certificate nginx/apache. You need a full bundle certificate.
