Hi Team,
Thanks for using the Wazuh.
The image you shared I can your filebeat is not able to communicate to your Elasticsearch.
Can you please check your Elasticsearch if you are running it on IP instead of localhost and update it correctly into the filebeat.yml file.
if possible can you please share the configuration file of Elasticsearch and Filebeat so I can review them and help you better.
Hope this information helps you. Please feel free to reach out to us for any information/issues.
Regards,
