What does that mean, in terms of "traffic to the IP address gets sent

That suggests that all incoming traffic to your IP on port 443 gets sent
to server#1.

What request do you make that returns the 404 error?
What response do you want for that request? (Probably something like
"http 200 and the contents of *this* file".)
(And: what does the nginx log file say about the 404 error? Is it trying
to read a different file from what you expect?)

With that config, your server#2 will not see a Host: header that includes
threedaystubble.com.
If your server#2 needs that Host header, things will probably break.

If that is the entire config on server#2, it should probably work. But
if you have more server{} blocks, such that the "default" port-80 server
is something else, then that extra config might be causing this not to
act in the way that you want.

Depending on what else is wanted, I'd suggest one of the methods to
make sure that the Host: header that you want, is sent to server#2 in
the proxy_pass request from server#1.
That can be proxy_set_header; or proxy_pass with the hostname and either
an upstream of the hostname, or the system resolver to refer to the
server#2 address.
(Or: just use port 8080 on server#2 for this site; and port 8081 on
server#2 for the next site.)
Good luck with it,
