Steps to reproduce:

1. Use MS Teams webhook template
2. Use instructions in said template to configurate MS Teams and Zabbix
3. Make intentional configuration error on Zabbix side - incomplete webhook adress paste into Media configuration
4. Prepare Host, trigger, trigger action
5. Trigger a problem
6. Wait for Zabbix to fail 3 attempts to send message to Teams
7. Check error message in Teams
8. Check server logs

Result:
Zabbix frontend response:

Server logs:

67174:20260325:144523.487 [MS Teams Webhook] FAILED with response: 
 67174:20260325:144523.487 [MS Teams Webhook] notification failed:

 67173:20260325:144543.503 [MS Teams Webhook] notification failed: 

Expected:
Atleast on server log level some more information on where failure appeared
