Unable to connect to internet after first startup

Hi everyone, I’m having trouble setting up my yellow for the first time. Upon receiving power, the red LED goes on and the yellow LED flashes for ~10 seconds before turning solid. Using the serial monitor, I can see it’s stuck at these lines, presumably because it can’t connect to the internet:

Welcome to Buildroot
yellow-installer login: [   15.711325] haos-flash[229]: Getting latest Home Assistant OS version from channel stable...
[   15.749090] haos-flash[232]: curl: (6) Could not resolve host: version.home-assistant.io
[   17.492738] vc4-drm gpu: [drm] Cannot find any crtc or sizes
[   36.032783] cam-dummy-reg: disabling

I have it connected to a Eero router and the weird thing is I can see it in the app as “yellow-installer”, but going to that IP address or http://homeassistant:8123 times out, as does running ping. Anyone have guesses on what I could try next? One note, I bought the PoE kit but am using a 12v barrel plug for power

Just solved my issue, I think. Had to change my Eero’s DNS resolver from the ISP default to 8.8.8.8
