Hello Gabriel,

If Firefox says "unable to connect", it means nothing is listening (or it’s blocked).  

Some quick diagnostics: run this on the terminal ss -tulnp | grep 443. From the response, you should see if the dashboard is listening on that port. and this: lsof -i :443

Check the configuration for the dashboard here: /etc/wazuh-dashboard/opensearch_dashboards.yml

Ensure the ports and IP are specified, you can check the attached image for reference.

server.port: 443
server.host: 0.0.0.0

Then please check the logs too:

journalctl -u wazuh-dashboard | grep -i -E "error|warn"

Lastly, you can also try another browser or incognito mode to test this. Because you did an upgrade, the dashboard may not be binding to 443 or another service took that port.

Please let me know what you find.

Hello Gabriel,

The main issue is that your Wazuh Dashboard is failing to start because it cannot find the SSL certificate file: /etc/wazuh-dashboard/certs/dashboard-key.pem

This can happen after an upgrade where the certificate files are removed, paths change, or there are permission issues.

Because of that, the dashboard is not actually running on port 443, which is why your browser shows “unable to connect."

To confirm this, you can check: ls -l /etc/wazuh-dashboard/certs/

If the cert is missing as indicated, you can restore or recreate the missing certificates.
Ref:
https://documentation.wazuh.com/current/user-manual/wazuh-server-cluster/certificates-deployment.html

Another error seen is: [ConnectionError]: connect ECONNREFUSED 127.0.0.1:9200

This means the Dashboard is trying to talk to the Wazuh Indexer, but there is no response at port 9200. This usually happens because:

The OpenSearch service isn't running, or there is an underlying issue there too. Check the logs and share what you find: cat /var/log/wazuh-indexer/wazuh-cluster.log | grep -i -E "error|warn"


Let me know what you find.
