I don't fully understand what you are trying to do here.

For example -- what do you mean by a CNAME redirect?

server_name *.tinyadults.com;

(See http://nginx.org/r/server_name)

Or, if the names should be handled differently:

server { server_name abc.tinyadults.com; }
server { server_name xyz.tinyadults.com; }

Ok. Does your nuxt.js service care whether the original request was for
the hostname abc or xyz? If so, you may want to indicate to it what the
original hostname was.

I don't know what you mean by that.

Might it be

server { server_name abc.tinyadults.com domain1.com; }

or perhaps

server { server_name domain1.com;
location / { proxy_pass https://abc.tinyadults.com; }
}

?

Can you give some specific examples of "I make *this* request, and I
want to get *this* response"?

It looks like you have a nuxt.js http service listening on port 4001, and
you want an nginx https service to listen on port 443 and reverse-proxy
the 4001 service.

But your suggested nginx config seems to try to do something different
from that.

Good luck with it,
