Qualys scanners use the ssh-rsa algorithm for pubkey signing in its attempt of SSH login. Modern SSHD servers reject pubkey login with ssh-rsa, so Qualys is unable to scan up-to-date Linux e.g. Debian12 or RHEL9. Qualys does not check the list of pubkey signing algorithms accepted by SSHD servers, and therefore cannot notify about any insecure ones.
