Zerossl/Let’s Encrypt certificate for ASA

[Gagovski]

Hi,

I am trying to install a identiy certificate on my ASA using this guide: 
https://www.ipconfigz.com/installing-a-free-certificate-on-a-cisco-asa-firewall-for-anyconnect/

ASA-Version: 8.4(2)
ASDM-Version: 7.1(1)

I do everything as said in the guide but when I try to install the new certificate using ASDM I always get this error:  "Error: Import PKCS12 operation failed."

Can you help me to fix this please? I really don't know what I am doing wrong here.

ok, after messing around for 2 days and trying and retrying everything again I finally fixed it.
--> a reboot of the ASA was needed, then the import worked.
