Connect to “MODEP” Wi-Fi hotspot using my macOs 10.12.6

Hi, i’m newbie on Rasp…
i have a pi4 4gb and installed Patchbox with MODEP module.
I’m using an Yamaha usb class compliant audio card 24bit 192khz.
This is what i’ve done:
I install Patchbox - manage Wifi hotspot- enabled Wifi hotspot.
I try to connect to it with Chrome web browser and type address [http://172.24.1.1].
But i’ve this message: ERR_CONNECTION_TIMED_OUT.
Please tell me what i’ve done wrong???
Many thanks guys
