Samsung ST and Harmony Elite sync problem

I’m trying to connect SmartThings with Harmony Elite remote control. But the error message states: “Sorry we are not able to retrieve devices from your SmartThings account”

How to fix it?

Did you ever solve this ? The Elite looks NICE, how do you like it. I miss having a screen on my Harmony. Not sure I am willing to go for $320 but I do like the looks of this remote.
