Alarm “Device certificate status expired: it cannot be renewed” on panorama every day.

[CyberEye]

Hi Folks,

I am getting the below alert in the panorama every day. I found the below article for resolving the issue.

My concern is 

1. Why is this necessary? I've never had the issue before v9.1.x

2. Do I need to do this every 3 months from now on?

Issue: Alarm “Device certificate status expired: it cannot be renewed”

Thanks,

Robin

Hi Robin

if the firewall is able to connect to the update server it should be able to renew the certificate by itself. there may be something being blocked or somthing may not be resolving in DNS (check logs for any dropped connections)

the device certificate is used to connect the firewall to cloud services like cortex data lake, but they made it pretty annoying to not have a certificate even if you don't need one as it keeps spawning error messages as long as the certificate is not 'green'

Dear @reaper ,

Thanks for the response. In my panorama, the last time I manually renewed the certificate and showed not valid after 3 months.

Now(after 3 months ) showing the error "Device certificate status expired: it cannot be renewed" so it will renew automatically after every 3 months if the required communications are allowed? I mean for certificate check OSCP should be allowed?

On our FW's in many different configs we get error:

Failed to renew device certificate. Failed to send request to CSP server. Error: No OCSP response received(dest => 35.238.43.180)

They are able to resolve DNS and nothing is blocked, so it seems there is some error on the OCSP server?

Same problem here.

A single PA3020 did not renew the cert.

I opened 2 days ago another thread.

Today i requested a new cert with OTP as a workaround. Will see what happens in 3 Months or if there comes up another solution.

hi Robin

Upon closer inspection several of my firewals are displaying the same issue, PANW may be having an issue with their OCSP server

As i mentioned in my post Failed to renew device certificate :

The Root CA Palo Alto Networks Inc.-Root-CA G1 that signed the cert for certificatetrusted.paloaltonetworks.com is not trusted if you browse to the url. But i do not see any deny or block or other errors concerning this.

I did not find any other clues for the problem.

I resolved this today by removing my zone protection profile from my management network. I believe SYN Cookies (or something else) may have been interfering with this renewal process.
