SSL Handshake between Java Server with Netty Frame and C# Client with dotnetasyncsocket

Question

The client can receive the certificate from the server with remotecertificatechain errors but the java server throws an error null cert chain.

I passed a keystore in java while I use a .crt certificate as to c# client. I have imported my client certificate to server certificate.

I have noticed that during the handshake, when the java server accesses the getAcceptedIssuers, java netty servers throws an exceptioncaught:

WARNING: Unexpected exception from downstream.

Any idea why this is happening? Any suggestions to solve this? :(

Answering my own question, turns out that there was no problem with the code! it's with the self signed certificate on the client side. I used keytool of java to make the self signed certificate but it didn't work when i used this certificate on c# client using dotnetasyncsocket. So what I did was obtain a certificate signed by CA on http://cert.startcom.org/ that is for free.
