APNS : openssl s_client gethostbyname failure

Question

I'm trying to test the connection between my server & Apple's sandbox APNS server with the following command:

$ openssl s_client -connect gateway.sandbox.apple.com:2195 -cert cert.pem -key key.pem
Enter pass phrase for key.pem:
gethostbyname failure
connect:errno=0

What is the meaning of gethostbyname failure, and what is the cause?

In the same server, telnet to port 2195 is working fine:

$ telnet gateway.push.apple.com 2195
Trying 17.149.36.242...
Connected to gateway.push-apple.com.akadns.net.
Escape character is '^]'.

UPDATE: If I use IP instead of host name, it works fine:

$ openssl s_client -connect 17.149.36.242:2195 -cert cert.pem -key key.pem

OpenSSL is unable to resolve DNS ?

The correct name for sandbox is gateway.sandbox.push.apple.com, not gateway.sandbox.apple.com.
