1st Day - New User - Can’t Access

I just purchased and ODroid Pre-Installed. Installed and hooked up to network. It is not accessible via http:// home assistant.local:8123 or via http://myHAIPAddress:8123. I’ve dug and searched. I messed with router settings. I’ve dedicated that up address. No luck. Frustrated on day 1.

Can you ping the ip address on your network?

Yes. I can ping the ip address.

Anyone have any ideas?

I would contact the seller that pre-installed HA.
