First time setup Volumio 3 on Pi4 b issues

i have been looking up and down for a solution but i couldn’t find one.
follow the instruction to DL and write the image to SD card and power my Pi4 on
waited after 15-20mins, i can see the volumio got an ip from my router, but it’s ssh and http are not listening. refuse to connect.
using the hotspot setup, every time i try to connect with password volumio2, it said failed to obtain IP.
Does anyone have seen this?

the last thing I want to do is plug a monitor into it and troubleshoot this way, as this should be headless…

Did you connect from a web browser on device on the same network using the IP?
Info
SSH is disabled by default.
