Anyone got WordPress Multisite using subdirectories working on NginX - with each site serving to https only?

I’ve run up my old Ubuntu 12.04 WordPress Network site using Apache to a brand new 16.04 Nginx instance. The main site is working fine, but I can’t get it to serve any of the subdirectory site contents in my network. I’ve installed the NginX Helper plugin, have Lets Encrypt Certs in place for the main site and the first of 7 subsites, but all I get is permission errors or the NginX welcome to your new website page.

Any ideas what i’m doing wrong?
