Hey, I’m new here, and also very new to HA, so apologies if this is a stupid question.
Yesterday I set up HA without any issues, but this morning I’m unable to connect via http://homeassistant.local:8123/ - I can connect via the IP address, but I’m curious as to what I’m missing here?
I believe .local is simply the default domain used by a router running the Multicast DNS protocol. I have also seen that some web browsers will do it automatically while others don’t.
As others have said it’s a dns issue on your system, not a HA issue as such. You can add homeassistant.local to the hosts file on the computer if it really bothers you.
I yesterday also got the same issue.
If you enter the url http://homeassistant.local:8123/
then make sure that under “settings” → “network” the hostname is the same.
