PKCS#12 certificate import not working on 7.2.2

RouterOS General

I’m trying to import a PKCS#12 certificate and key under 7.2.2 and it’s not finding anything inside the P12 file.

/certificate/import  file-name=test.p12 passphrase=fd6eef05 
     certificates-imported: 0
     private-keys-imported: 0
            files-imported: 0
       decryption-failures: 0
  keys-with-no-certificate: 0

I’ve double checked the file (downloaded from the RB5009 to my desktop) with openssl and all the certificate and key were all there.
I use it (with a script) to upload my LetsEncrypt certificate periodically. Worked like a charm for months, including some 7.x versions (I don’t recall last time it worked, so I’m not sure of the exact version).

Any ideas?

Usually this indicates the certificate is in the store already…

Last time I tested it worked for me, but that was some weeks ago already - I can not name the exact version.

Thanks for the pointer!
I’ve checked that already. But reminding of it gives me a hint. I will remove all certificates (if I can export the CA key, used to sign several OpenVPN certificates) and give it a try.

The RB5009 is a fantastic workhorse, but I’ve already had two unfortunate upgrade episodes (one I’ve lost all the configuration and on the second I had to NetInstall). Maybe something related.
