Host does not connect to zabbix agent 2 without template

[markuman]

I've got a strange issue. I am creating hosts using ansible community.zabbix.zabbix_host that works perfectly

- name: configure zabbix hosts
  community.zabbix.zabbix_host:
    host_name: my.host
    interfaces:
      - type: 1
        main: 1
        useip: 0
        dns: my.host.tld
        port: "10050"
    host_groups:
      - Linux servers
    link_templates:
      - Linux by Zabbix agent
    status: enabled
    state: present
    tls_psk_identity: my psk identify
    tls_connect: 2
    tls_accept: 2
    tls_psk: "{{ lookup('onepassword', 'zabbix.agent.psk') }}"

When I remove the host and recreate it without a template (or just unlink the template) and add just a web scenario to it, the agent won't become available.

- name: configure zabbix hosts
  community.zabbix.zabbix_host:
    host_name: my.host
    interfaces:
      - type: 1
        main: 1
        useip: 0
        dns: my.host.tld
        port: "10050"
    host_groups:
      - Linux servers
    link_templates: []
    status: enabled
    state: present
    tls_psk_identity: my psk identify
    tls_connect: 2
    tls_accept: 2
    tls_psk: "{{ lookup('onepassword', 'zabbix.agent.psk') }}"

Furthermore, there is no error message. Nor on the client host in /var/log/zabbix/zabbix_agent2.log nor in the server log related to my.host.
Any ideas what's going wrong?

Why should it show agent availability if you have no items related to agent? Web scenarios are not executed on host, but on server/proxy. They do not need any agent. Server/proxy will never look for an agent, that has no items...

The steps are periodically executed by Zabbix server in a pre-defined order. If a host is monitored by proxy, the steps are executed by the proxy.
