Zabbix 6.0 HA, configuration and media types problems

[BEDTr@veler]

Hello everyone!

I configured Zabbix 6.0 HA.
I used zabbix-mon-01 and zabbix-mon-02 as zabbix nodes, zabbix-sql-01 as sql server.
After configuring server according to official documentation - servers switching correctly.
My main zabbix server is zabbix-mon-01 (10.10.190.101), secondary server zabbix-mon-02 (10.10.190.102).
If I turn off zabbix-mon-01, web interface over 10.10.190.101/zabbix not respond. I can get access over zabbix-mon-02 (10.10.190.102/zabbix).
In this way my media types - MS Teams not working because macros {$ZABBIX.URL} saved as value http://10.10.190.101.

How I can get access to web interface zabbix using only one ip address?
How I can fix MS Teams notification?

Thank you for any help.

Install separate web frontend... I just don't understand this building HA, but leaving 2 possible frontends..
You can of course make things complicated and use VIP address, what you can move around with keepalived between those 2 servers and configure both frontends to use that VIP. You can do that of course with separate frontend hosts also to gain HA frontend..

Thank you. I don't thought about it for High Availability.

I used service Keepalived for VIP address. All working correctly, acording to this manual
