(newbie) Problem connecting with a specific server

[paul anderson]

I am having a problem using openssl s_client to connect to the following server: 156.77.100.189:443   When I try to connect, I get an ssl handshake failure.  I suspect this has something to do with the fact that I am using the supplied test certificates, but being a total ssl newcomer, I don't really know.   This is the command I have been running in the apps directory:   ./openssl s_client -connect 156.77.100.189:443 -cert ./client.pem   This works just fine for a few other addresses (208.213.98.243, 193.67.236.124), but I get the following error for that particular server:   "12974:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:203:"   Any help would be greatly appreciated.
