Cisco ASA Unable to parse CRL

Kliwer · ‎08-07-2024

Hi.

I am trying to setup CRL on ASA 9.20 on Cisco Firepower 1010 but when trying to request crl I get "Unable to parse CRL".

I tried PEM and DER, always the same.

debug crypto ca 14 gives:

My local CA is setup according to this guide: https://jamielinux.com/docs/openssl-certificate-authority/certificate-revocation-lists.html

What can I do to make it work?
