So far I've managed to install Wordpress Multisite, with network domain of domain1.com
Each site in the network uses its own domain. E.g, www.domain2.com
I set up each network site using wo, namely:
wo site create domain2.com --wp --letsencrypt
I then edited the nginx conf file for each network site so that its root points to that of domain1.com.
Where I am now at is that I need to have non-www redirect to www version for all sites.
I've tried a few things, from suggestions in the WO support forums, and from elsewhere. I've got as far as http non-www redirecting to https with www. But if I put in https non-www, it redirects to the primary network domain (domain1.com).
I'd be very grateful to hear what the recommended approach is for this.
