[Help-gnutls] Another one: A TLS packet with unexpected length was received. |

Hello everyone,
i am currently implementing a handshaking procedure. Everything works
fine when the client chooses not to use TLS. But when TLS is requested,
the gnutls_handshake() fails.
The client reports the following error: GNUTLS ERROR: A TLS packet with
unexpected length was received.
The server reports no error, because gnutls_handshake() seems to wait
for something and just blocks.
Here is some debug data (loglevel 7).

--------------------------------------
As there seems to be handshaking conversation and the client starts the
conversation I don't know where to search for the error. Client and
server and both on the same machine, using the same GNUTLS library.
Can anybody help me?
Thank you!
So long
