So, when you had reconfigured this service, you could not deploy, right? If so, did you have a close look at all the warning and/or error messages shown when the deployment fails? They appear in the GUI, but as a rule are quite long, so you have to scroll a bit. (If you wish, I can also give you a command-line alternative for your Icinga server’s Shell, to produce the same warnings/errors.)
P.S. (late edit): In fact, regarding the Shell command, I see that community co-member log1c already did so in this older Director thread - check out their only posting there, last line.
