Certificate is expired and is shown in the browser

[jasfree]

Good Morning,

System: PA-3020

SW Ver: 8.0.6

we are trying to implement a certificate on our Test Firewall and have encountered the an expired certificate.

We have created the certificate (self-signed); however, when I go to the Palo Alto GUI, the browser says 'Not secure.'

The information from the certificate shows that the certificate was valid from 16 December to 18 December 2017. It does not show up under Device->Certificates. I have implemented a new certificate; but all browsers that I use become the certificate shown above.

After creating the new certificate, a 'commit' was executed, but we are still getting the old certificate.

My Questions are:

    1. Why is this certificate being selected?

    2. How can I delete this certificate.

Thank you for your help.

Correction: The certificate is not expired, 

Apperently it is a support certificate that expires in 2027.

The problem is still that it doesn't show up under Device->Certificate.

Hi

This is the default factory certificate, it is not listed in the certificate store

To replace it with a different certificate, you will need to first import one with it's intermediary or root, then go to the Device > setup > management > general settings option, and set an SSL/TLS Service profile containing your new certificate

Hi reaper,

Thank you that really helped.

Question:

will the certificate config be synchronized in a HA configuration. Or, do I have to repeat the process on the Partner HA device?

I'm assuming that the certificates are hardware dependent, because I don't see the self-signed certificate from the master device.

Certificates are virgin territory for me.

Thanks in advance.

Here you will find which settings do and don't sync exactly :
