x509 Certificate cannot import since 7.7

Hi there.
Cannot import x509 certificates since 7.7.
Tested up to 7.9RC3

According to official Mikrotik v7.7 changelogs under certificate:

*) certificate - improved Let’s Encrypt logging and error recovery;
*) certificate - improved certificate management, signing and storing processes;

Nothing noted… Yet many forum entries…

CA crt can import successfully:

#openssl x509 -in ca.crt -text

Signature Algorithm: sha512WithRSAEncryption
        Subject Public Key Info:
            Public Key Algorithm: rsaEncryption
                RSA Public-Key: (4096 bit)

Client Certificate cannot import:

#openssl x509 -in client.crt -text

Signature Algorithm: sha256WithRSAEncryption
        Subject Public Key Info:
            Public Key Algorithm: rsaEncryption
                RSA Public-Key: (4096 bit)

SHA256 deprecated? If so, mind telling the peasants as well?

Regenerated client certificate with sha512WithRSAEncryption, no passphrase
OpenSSL 1.1.1k FIPS 25
No joy. Still can’t import it.
Mikrotik support. You know about this?

Please send to support@mikrotik.com a certificate you are trying to import.

#[SUP-114596]: x509 certificate cannot import since v7.7 was logged 26-04-2023…

Its been a long time.

Was made aware by Mikrotik Support that we should not be making use of “-addtrust clientAuth” in OpenSSL while creating certs.
