Hello hamdifawas, sorry for the late reply.
What version of the ova are you using? In principle this can be due to several causes, can you check that the services are up and running?
- systemctl status wazuh-manager
- systemctl status filebeat
- systemctl status elasticsearch
- systemctl status kibana
We are also going to check the status of filebeat and the elasticsearch cluster:
Regarding the logs, it is expected to find some ECONNREFUSED messages, but the one we are seeing regarding getApiInfo, not.
Have you modified any user or any user permission?
Regards, Raúl.
