I’m writing a program in java that send official invoice information to the Fiscal Administration. This public service provided certificates to use in the SSL connection to the web services and to encrypt some especial data fields inside the request body message.
I’m having an EOFException error during the handshake phase after client and server have agreed to communicate using the agreed cipher suite that in this case is TLS_RSA_WITH_AES_128_CBC_SHA.
Following the SSL protocol the client perform with success a test using the new cipher and send the test data to the server so the server can also repeat the same test and confirm that it is also capable of encrypt and decrypt data. And in this point the server send the EOFException.
Here is the last part of the SSL communication log:
Send a quick confirmation to the server verifying that we know the private key corresponding to the client certificate we just sent...

I have no idea on what might be the cause for such a failure and how to programmatically influence the outcome of this step in the process. I’ve tried force the use of other ciphers recognized by both client and server such as SSL_RSA_WITH_RC4_128_MD5 but the error remain. Any thoughts on how to solve this problem?
EOFExceptionerror'. The server closed the connection, which caused the client to get theEOFException. – user207421
