Another thing to check is to make sure
you've actually built OpenSSL with KTLS support
(should be no OPENSSL_NO_KTLS defined in generated includes).

As previously provided, you have several --with-openssl-opt:
--with-openssl-opt=enable-ktls --with-openssl-opt=enable-tls1_3

In this case, only the last one is applied.
To specify several values: --with-openssl-opt="opt1 opt2"

It's also useful to know the actually negotiated ciphersuite.
