Hello! been trying to do a standard HAOS install onto a RPi4 since yesterday, but it keeps failing. after flashing the image via my PC and putting the SD card into the RPi4, the the setup page (homeassistant:8123) does not load. It seems the RPi4 does not boot as nothing shows on the screen when i plug a monitor via HDMI, and ethernet activity light remains off. Also, solid red and green LED on the RPi4.
Any suggestions? i know the RPI4 and the SD card and the ethernet cable and PS are are all fine since I was previously using them for a Pi-hole
