I think they’re already there though

*.example.com like network.example.com only covers sub domains and not third level domains like host1.network.example.com or *.network.example.com

get a wildcard like *.example.org and you’ll be done for everything

This actually only covers the subdomain. It doesn’t extend to *.network.example.com. I spent last Saturday fighting my browsers until finding that out.

I dunno what you guys are doing that makes your nextcloud die without touching it

Mine runs happily until I decide to update it
