Can't pass Kim's first trial

Idk why, but I can’t connect the three combos (downLP -> HK -> Hangetsuzan). Is it my fightstick’s problem? I’m using Qanba Q1 with no replaced parts. It’s just so hard to execute. Anybody willing to educate me?

The cr.LP xx cl.HK cancel is quite late. cl.HK xx HK Hangetsuzan has to be done pretty fast though. Practice the two cancels separately so you get a feel for them, then put them together.
