--min-tls=1.3
Why it's wrong here
This is an invalid flag format for the kube-apiserver.
- ✓
--tls-min-version=VersionTLS13
Why this is correct
VersionTLS13 restricts secure connections exclusively to TLS version 1.3.
- ✗
--cipher-suites=TLS_AES_256_GCM_SHA384
Why it's wrong here
Cipher suites specify encryption algorithms, whereas --tls-min-version controls the protocol version.
