ASA Error for Unknown Certificate

DStringfield

Hi all, 

 

I recently renewed some SSL Certs for my ASA5506x devices. I am now getting an error (repeatedly) which claims that the verification of a cert chain is failing. However I cannot for the life of me find the certificate that it is referencing. 

 

The error as it appears in the logs is here:

%ASA-3-717009: Certificate validation failed. No suitable trustpoints found to validate certificate serial number: 0509, subject name: cn=QuoVadis Root CA 2,o=QuoVadis Limited,c=BM, issuer name: cn=QuoVadis Root CA 2,o=QuoVadis Limited,c=BM .
%ASA-3-717009: Certificate validation failed. No suitable trustpoints found to validate certificate serial number: 7517167783D0437EB556C357946E4563B8EBD3AC, subject name: cn=HydrantID SSL ICA G2,o=HydrantID (Avalanche Cloud Corporation),c=US, issuer name: cn=QuoVadis Root CA 2,o=QuoVadis Limited,c=BM .
%ASA-3-717009: Certificate validation failed. No suitable trustpoints found to validate certificate serial number: 3000683B0F7504F7B244B3EA7FC00927E960D735, subject name: cn=tools.cisco.com,o=Cisco Systems\, Inc.,l=San Jose,st=CA,c=US, issuer name: cn=HydrantID SSL ICA G2,o=HydrantID (Avalanche Cloud Corporation),c=US .
%ASA-3-717027: Certificate chain failed validation. No suitable trustpoint was found to validate chain.

 

Using the CLI to find all the certs gives this result (sanitised slightly) 

 

Result of the command: "show crypto ca certificate"

You will hopefully agree that the certificate it's complaining about above is not listed, hence my confusion.

 

Thanks!

I suspect smart call-home has been enabled.That happens via https and requires you trust the Cisco certificate and its issuing and root CA.

Your errors include a failure to trust

tools.cisco.com

...and the issuing and root certificate above it. You can either disable SCH ("no service call-home") or add the necessary certificate and chain of trust. Details for the latter option can be found here:
