Currently, we try to switch from Zabbix 6.2 to 7.0-2 for our new clusters (i.e. those do not have Zabbix 6.2 preinstalled, but we install 7.0-2 directly). However, while 6.2 runs without any visible issues, 7.0-2's server stops after start. I am primarily looking for ways to debug this problem further, but if someone has straight up a solution, I am all there fore it.
The log indicates that it is a dns issue:
We do use [dnsmasq](https://thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html) but had no issues with Zabbix 6.2. Name resolution via dnsmasq works in general.
In order to install Zabbix we make use of an [Ansible](https://www.ansible.com/) playbook:
## Additional
There are more tasks running (like setting up the zabbix-agent and a web view), but those are unrelated to the problem, I think.
I have omitted the tags Ansible and dnsmasq on this question for now, because narrowing down on the problem is probably just a zabbix question and I don't want to discourage potential answerers by adding a tag they might be unfamiliar with.
