Your connection is not secure

[Nirali Soni]

Hi all,

I have setup DevNet Sandbox Lab. But when I tried to open CUCM admin page it's giving me an error of "Your connection is not secure".

I  am using "https://<cucmpubip>/ccmadmin/index.jsp".

Please let me know what should I need to update in here.

Thanks

Hi Nirali,

By default CUCM uses Self-Signed Security Certificates. If you would like to establish a secure connection with CUCM then you need to install signed certificate from trusted Certificate Authority (CA). You need to install signed certificate for Cisco Tomcat Service . There are two options for CA: 1. Private or Internal CA (i.e. Microsoft CA Server) 2. Public CA (such as GoDaddy, Verisign etc.).

Please go through the Security Guide for Cisco Unified Communications Manager. You can also refer to below support URL:

You can simply download the root CA for the self signed certificate, install it in your machine, and login using the CN of the tomcat certificate

Hi Jaime.

Where I can download the Root CA from ?. because in the Certificate Manager, tomcat certificate only I can see Cert.PEM. Or is it necesary to sign a certificate with a CA, to avoid the security GUI error.

IP X.X.X.X usa un certificado de seguridad no válido.

Este certificado no es confiable porque está autofirmado.

Código de error: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT
