Off to a bad start

Hi guys, non technical user here and have been dreading getting dappnode up and running.

I am stuck on step “3. Set up the Access to the UI”. I have tried local proxy and wifi access but neither seem to work. I am getting messages in my browser that it isn’t secure and things like " my.dappnode’s DNS address could not be found. DNS_PROBE_POSSIBLE"

Does anyone know how I fix this to get access?

Is their an official discord?

Thanks
M

Wow. Really good tech support.
