OpenSSL Connect command error

Question

Hi,
 I have installed OpenSSL in Windows server 2008 R2 and created a CSR, 
Now i want to connect the Registry Portal  using the Connect Command in OpenSSL
(command:openssl.exe s_client -connect host:port -tls1 -cert cert.pem -key key.pem -CAfile cacert.pem).
when i connect with this command it shows an error message

Loading 'screen' into random state - done
connect: No such file or directory
connect:errno=0

How to solve this issue...?
