Failed to renew device certificate

[kbe]

Hi

the device certificate is going to expire end of march.

My PA trys to renew it and comes up with the following error:

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

I have no telemetry enabled.

Just activated the certificate with OTP on 2020/12/29 after upgrading to PanOS 9.1.7.

Now it´s the first try of my PA to renew it.

The only thing i found relates to PanOS 9.1.8 wich seems to fix another error with device certificate:

Fixed an issue where the firewall returned the following error message when attempting to request a device certificate using a one-time password (OTP): 

invalid ocsp response sig-alg

Any ideas where to look for?

TIA

Have you checked your conectivity to certificate.paloaltonetworks.com?

I've just installed a new certificate for a Panorama, worked ok.

Last traffic to ( url eq 'certificate.paloaltonetworks.com' ) was on 12/29 when the certificate was installed the first time.

No block / deny or other traffic to this url or ip since then.

Seems the PA ist trying to connect to 35.238.43.180 and there is no deny for it.

The mgmt interface has an allow rule but the renew is not working.

This was the traffic from the last 2 days to https://certificatetrusted.paloaltonetworks.com/

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 that should not be the problem.

I have exactly same problem on many devices in different configurations. Nothing is blocked, DNS resolves OK.

Today i requested a new OTP and choose to Get Certificate on the PA which revokes the actual cert and requests a new one.

The new Cert request finished without problems.

Now i wait til 16-06 to see if the next renew will work automatically or if the problem comes up again.

same problem here, i also renew the certificates using one-time password.

allow app 'paloalto-shared-services' to mgmt console rule, your most likely getting blocked. I was

Thanks, this is what helped me with getting the device cert installed on a couple of new firewalls.

My cert expires in 31 days and I see no way to renew it.  I don't have a way to track the firewalls attempts since this happens via the mgmt interface.  All I see is the graphic below and it doesn't look like it's tried to connect to the server since the cert was issued.  

How do I renew it?

[kbe]

The Palo normally fetches a new cert by itself before the other expires. There should be no need to get it manually under normal conditions.

I see a link with get certificate wich i used the last time (see my older posting from 2021-03-18).

[Jason_Lieberman]

I have no such link.

Hi @Jason_Lieberman ,

There's a way to fetch it using the CLI:

admin@PA-LAB> request certificate fetch otp <value>

replace <value> with the OTP generated on the support portal.

Hope this helps,

While the 'request certificate fetch otp' is not a valid command on my 440.  'request certificate fetch' is.  When I ran that is managed to get a new cert.  I'm shocked!  It's been failing for a few weeks now and TAC is stumped as to why.

Thank you for that.

Try the solution here on the 440 - it works luckily : https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u0000004NlxCAE

Then ssh in and try simply:

 request certificate fetch
