You can put multiple names in a single server name directive, don't use multiple directives

To clarify, you CAN edit the default site conf to modify or add server blocks. Alternatively you can add more site conf files like you did. Either works

Main conf is /config/nginx/nginx.conf, which includes (imports) /config/nginx/site-confs/default, which contains the main server block and it also includes (imports) all the proxy confs Check out the examples in the default site conf

If you're doing dns validation, you can get wildcard for b by setting extra domains to "b.com,*.b.com" Then to serve wordpress at b.com, set the server name for the wordpress server block to b.com

Then you'll have to create a custom script that does those steps for you during container start: https://blog.linuxserver.io/2019/09/14/customizing-our-containers/

How did you update it? The bionic repo has 2.17

Yes

That's a question for unraid and/or CA

Perhaps live server needs to bind 0.0.0.0 so it's accessible from outside the container as opposed to bonding 127.0.0.1 which would only be accessible from inside the container

That's correct. You need to enter your network subnet in the gui settings for it to nat

And it's udp (by default)

No

No, nginx would have to be compiled with it

passwd username won't work because it's not using pam See the readme instructions about disabling the "admin" user, reverse that to re-enable admin user, restart container, log in with "admin/password", make your changes to your main user, and then disable admin user again.

Create a cname in cloudflare with just an asterisk as the name "*", pointing to the A record for your domain and that's it. Then in swag docker settings, set the subdomains variable to "wildcard" without the quotes.
