waiting for API ends with error

[badummtss]

|Wazuh version|Install type|Action performed|Platform|
|4.9.1|Ansible|TASK [../roles/wazuh/wazuh-indexer : Wait for Wazuh indexer |Ubuntu 24.04

I'm testing out the new 4.9.1 version with ansible as cluster configuration.
I have 3 lxc's on Proxmox created for that (all of them created with terraform).
I used this document https://documentation.wazuh.com/current/deployment-options/deploying-with-ansible/guide/install-ansible.html for installation.

On two of my nodes everything seems to be fine, on one I get the following error:
FAILED - RETRYING: [ct-xxxx]: Wait for Wazuh indexer API (22 retries left) and
fatal: [ct-cl-wazuh-02.loc]: FAILED! => {"attempts": 24, "changed": false, "content": "OpenSearch Security not initialized.", "content_length": "36", "content_type": "text/plain; charset=UTF-8", "elapsed": 0, "msg": "Status code was 503 and not [200, 401]: HTTP Error 503: Service Unavailable", "redirected": false, "status": 503, "url": "https://127.0.0.1:9200/_cat/health/"}

Could anyone help me out to fix this?
