Please share the full output of:
and also: sudo systemctl status wazuh-dashboard and systemctl restart wazuh-dashboard
Also verify the indexer health directly:
curl -k -u admin:password-here https://localhost:9200/_cluster/health?pretty
Along with the logs: cat /var/log/wazuh-indexer/wazuh-cluster.log | grep -i -E "error|warn"
systemctl status wazuh-indexer.service
How did you reinstall the Wazuh instance, and what prompted it? Did you perform a clean install by removing all the components?
Please let me know what you find
