Just got OctoPi set up, but am unable to reach it via the name octopi.local, only the IP. I am using macOS Sierra version 10.12.6, a Raspberry Pi 3 Model B, OctoPi image 2017-06-21-octopi-jessie-lite-0.14.0.img, and OctoPrint Version 1.3.6. Based on this FAQ, it seems like the name should just work. I'm only trying to access from home and I've also tried octopi.lan which doesn't work either. Any ideas? Thanks!
Connected via Ethernet or WiFi?
What browsers you using or tried?
Can you connect to it thru the terminal?
I am having the same issue. After just installing octoprint on my RP3 and going to http://octopi.local using both safari or chrome, I am not able to access OctoPrint from my browser. I am using a Mac and use both http or https just like instructed.
I've also tried to access it via its IP address and no luck.
If you can't even reach it via an IP address, something else is amiss. See this post:
If also added this to the original post for further troubleshooting.
Chrome, FireFox, and Safari
yes, but only using the IP
it seems to be a name resolution issue, but not sure how to resolve
"ping: cannot resolve octopi.local: Unknown host"
ping 192.168.1.20 or whatever you know the IP address to be. This will add it to your arp cache. I've seen this magically then work for name resolution.
If it were me, I would try to remote into the Pi using
ssh and then run an
ifconfig command to see what settings are being used for your connection. Here is the related portion from my own. The second line indicates the IP address, a correct netmask and broadcast address.
We see here that RX and TX errors are zero (I booted it about 30 minutes ago). We also see that there are a number of packets sent/received.

octopi.local is a manifestation of Bonjour (which should be running on a Mac). Find your DHCP server (usually your router), and use its web interface to see what name is associated with the IP address assigned to the Pi. If you use your router as your primary DNS server, then that name will resolve. In my case, octopi is all I need for a name (octopi.morgan.local if I wish to be formal about it )
I'm running Octopi 0.14 on a 3B and octopi.local hostname resolution is working fine for me. It's a little slow connecting, but it does connect. I'm on a MacBook Pro running High Sierra beta, but I can also connect from my iPhone and iPad.
If you're able to access OctoPrint via its IP address, make sure you didn't change the host name during setup. For instance I changed my host name to mk3, so I access via mk3.local
To check, ssh into your pi and run "sudo raspi-config". Goto hostname and check the name there.
