Zabbix and Telegram - Test works but Action does not

[lpossamai]

Hi all. I'm trying to get Zabbix and Telegram to work, using this article here.

The problem I'm having is that, when I test it using the "Test" button, it works. But when using it via Actions, I get: Sending failed: Bad Request: chat not found.

This is the Zabbix Server log:

38208:20220105:235544.577 [Telegram Webhook] HTTP code: 400
38208:20220105:235544.578 [Telegram Webhook] notification failed: Bad Request: chat not found

I've attached a screenshot of the user Media configuration.

What am I missing here?

Thanks!

Well. I re-imported the media type from here, and it worked! My mistake! Thanks!

There is an “IMPORT” button on the top right in the Media Types page (Administration > Media Types)

Hello, my server version Zabbix 5.0.19, can you help me to find the correct file to update?
