Problem with connecting poppy robot

Hi, I am newbie to this poppy robot
At present i have raspberry pi 4 and a sd card with poppy os(i have flashed it using etcher) and also
i have also installed the bonjour in my computer next
when i kept that sd card in the pi and waited for poppy-hotstop to appear in other computer wifi so that i can connect to it and acess poppy.local but i couldn’t able to see poppy-hotspot so i tired doing with ethernet, i have connected pi with my computer with a ethernet cable but when i typed http://poppy.local in my computer it is that page doesn’t exist or can’t find that page
So, can anyone tell me why i am making wrong, did i miss any step? or any suggestions?
