I am running Local 2.2.4 on a Mac with 10.13.4 (High Sierra). Local is working well on single sites, but I wanted to play around with a multi-site.
Using the default blueprint I am able to install a site, view the admin and the main site. However when I add a site to the network (using a sub-domain) it fails to load the new site.
I have tried this with and without docker fast boot. IPv6 is on since on.
