SSL chain not presented by BIGIP

openssl s_client -connect x.x.x.x:443 -key /config/filestore/files_d/www-qa_d/certificate_key_d/:test.key -cert /config/filestore/files_d/www-qa_d/certificate_d/:test.crt

are you doing client certificate authentication? if not, shouldn't it be CAfile option rather than cert and key?

e.g.

 config

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm virtual bar
ltm virtual bar {
    destination 172.28.24.10:443
    ip-protocol tcp
    mask 255.255.255.255
    pool foo
    profiles {
        http { }
        myclientssl {
            context clientside
        }
        tcp { }
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    vs-index 65
}
root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm profile client-ssl myclientssl
ltm profile client-ssl myclientssl {
    app-service none
    cert-key-chain {
        server {
            cert server.crt
            chain chain.crt
            key server.key
        }
    }
    defaults-from clientssl
}
