You're testing as root, which is not advised in terms of the core running as icinga user (a daemon, no shell, no .bashrc and such).

Your tests were done with "-H xio99cdejump02.example.com" while the command definition uses the $HOSTADDRESS$ macro, which then leads to the host attribute address with the value "10.xxx.0.110". So maybe it does not work at all as the manual tests resolve the fqdn to a different ip address in your dns? In order to fully expand the command the core would execute, go onto Classic UI - Service Details (extinfo.cgi) and click on "ACTIVE" where the link to the command expander is hiding. Right on, you should see all macros properly replaced (make sure authorized_for_full_command_resultion is set for your login name as well as access to resource.cfg is granted to the apache user). That way, you can become icinga user and copy paste the entire command then, avoiding manual thinkos. In terms of the error - tcpdump on 5666 on the client host, in order to see if handshakes actually happen.
