NSPanel Pro update to 2.4 problem

NSpanel Pro has downloaded the latest software version (2.4), I press the Install button under Software Update, a dialog box opens with information about the new firmware version, after which I press the Confirm button, after which nothing happens, the dialog just closes and goes back.

I had a situation where the window disappeared and after about 2 minutes the panel restarted and it was already talking about version 2.4.

I had the same thing.
