Kibana URL shows "Not Secure" when HTTPS enabled

[lcui_dxc (Li Cui)]

Hello there,

I enabled the SSL on ELK and now I'm able to log on to Kibana with HTTPS, but on the URL, it always show "Not Secure" in RED and the HTTPS in the url was crossed out in Red.
Is there anyway to get rid of this?

Many thanks

Li

@lcui_dxc,
What does your browser say when you click on "Not Secure"? It should give you more details about why it marks the connection is insecure.
The most common reason is that the TLS certificate you configured for Kibana is not signed by a trusted root CA.

Yes, the certificate is not signed by trusted root CA.... what we should to do get rid of that?

Thanks

Your best option is to generate a certificate that is signed by a widely-trusted CA. A popular free option is LetsEncrypt: https://letsencrypt.org/
