That shouldn’t make a difference as long as you’re running the latest public version.
This typically happens when communication between devices is somehow blocked at the router level – in some offices and large network environments this is usually the case. If you have a home router, I recommend looking into ensuring that there are no local firewalls in place on that router’s admin panel.
For a bit more background we use a really low level ‘bonjour’-based discovery system to see available devices, and then we use a random open port on the Mac to serve the Hype document. If you preview straight from Hype, you’re also running a server. Previewing on your Mac opens a browser with an URL like this:
http://127.0.0.1:53305/preview/1111F110-4C0F-4588-BA64-465F5F08EB4A-66066-0000545FEE797ABE/index.html
127.0.0.1 is your local address (this can be replaced with localhost, but if you instead replace this with your LAN IP address assigned by your router, any device on your network can load the page hosted from your server as well. You can get your LAN IP address by looking at your Network Preferences:
You would get a number like 192.168.97.12. You could replace that number and load the following URL on your iPhone:
http://192.168.97.12:53305/preview/1111F110-4C0F-4588-BA64-465F5F08EB4A-66066-0000545FEE797ABE/index.html
So if the URL you construct does not work, that means that either some sort of restriction on your mac is enabled or your router is blocking this type of connection.
