I guess the best way to diagnose this kind of issues would be to do a packet capture and compare the exchanged messages. That may require enabling decryption, which should be possible through the keylog file feature.

Here is a tshark command line I use:
$ tshark -o "tls.desegment_ssl_records: TRUE" \
         -o "tls.desegment_ssl_application_data: TRUE" \
         -o "tls.keylog_file: $PWD/keylog.txt" \
         -i lo -Px -O tls -Y "tcp.port == 443"

$ SSLKEYLOGFILE=$PWD/keylog.txt gnutls-cli ...
$ openssl s_client -keylogfile $PWD/keylog.txt -connect ...
