Looks like a valid spot to me. Spirits don't appear 100% of the time, in my experience, but four failures for a first meeting seems too much (repeat sessions can take many attempts, as they're probably tired of you). Also, I think it's important to start the waiting process in time, i.e. before the point of the night specified, although I'm not certain that's a factor.
In your case the partial screen shot mentions midnight, and if that's all it says (rather than before midnight, or something like that), then you should start during the previous time segment, in my experience (at least I've had more success with that timing, possibly 100% failure when starting during the specified time period).
