Why am I getting handshake error on cfhttp with SSL certificate?

We upgraded from CF9 to CF11.  We copied the cacerts file to the new server but now am getting handshake failure with cfhttp tag.  Spoke with tech on their end.  He said he sees the original request come in.  They send back their part of handshake and are expecting to see something from us which they are not.  Turned on SSL logging and can see the verbiage "valid certificate found".  It just appears that for some reason we are not completing the handshake.  All we see in logs after clienthello portion, serverhello portion, serverhellodone portion, is I/O exception handshake_failure.  Is there anything special in the CF11 upgrade that needs to be done in order to configure for SSL cfhttp tag to work?
