openssl is a command to perform tasks. VT100 is a terminal/display mode for a non-graphical access.

Does your C# script presents a certificate? What is it you are accessing?
It seems your error deals with renegotiation. Are you establishing a TCP session, exchange keys and then keep/maintain the TCP connection active?

From the error it seems that your process is establish a TCP connection exchange keys, and then while the connection is present trying to renegotiate the key exchange which is what the error seems to suggest.
If you must you should disconnect and restart a new connection if you can not maintain the same one with the exchanged keys you already have.

openssl is application that provides encryption libraries functions.
I think you might mean you are connecting to openssh.
You need to make sure that your C# application generates a local key, deals with key exchange to establish a connection.  Then your application will use the private key to decrypt the data and use the public key/certificate from the remote system to encrypt the responses/requests
