[openssl-users] Why was early data rejected?

[John Jiang]

I just build OpenSSL 1.1.1 on MacOSX.
Tried 0-RTT, and the commands like the followings,
openssl s_server -cert server.cer -key server.key -tls1_3 -early_data
-accept 9443
...
openssl s_client -CAfile ca.cer -tls1_3 -sess_in openssl.sess -early_data
data -connect localhost:9443

s_client reported
New, TLSv1.3, Cipher is TLS_AES_256_GCM_SHA384
...
Early data was rejected
Verify return code: 0 (ok)

What's wrong with my testing?
