The "New" here means that the resumption attempt failed. Successful
resumption is a pre-requisite for early data. How did you create
"openssl.sess"?
openssl s_client -CAfile ca.cer -tls1_3 -sess_out openssl.sess -connect localhost:9443
I just re-tried my test case.
Re-started s_server and did two connection. The second connection reported:
Reused, TLSv1.3, Cipher is TLS_AES_256_GCM_SHA384
Server public key is 256 bit
Secure Renegotiation IS NOT supported
Compression: NONE
Expansion: NONE
No ALPN negotiated
Early data was rejected
Verify return code: 0 (ok)

It looks the session was resumed, but early data still was rejected.
