I glimpsed on the trace and saw that it selects this ciphersuite:
<3>| HSK[8077a48]: Selected cipher suite: RSA_AES_256_CBC_SHA1
Something that might help in debugging without much fuss, would be
to test handshake by enabling other ciphersuites.
That would be for gnutls-serv to only enable:
a. key exchage: DHE-RSA cipher: 3DES
b. key exchange: DHE-RSA cipher: AES_256_CBC
c. key exchange: RSA cipher ARCFOUR
and return the traces if possible.
best regards,
