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.
