No worries.

Now that you have identified the problem, the possibilities for solutions
are more obvious :-)

For example, as an alternative to what you have already working, you
could note that you have the following line in your config:

proxy_set_header Host $http_host;

which sends the Host: header to the backend with the value of the
$http_host variable, which is the content of the incoming Host: header
(and may be empty).

If your backend requires that this always be "sample.com", then you
could instead use

proxy_set_header Host sample.com;

or possibly something like $server_name that has the same value.

Strictly, it might have no Host, or it might have a Host of
192.168.1.1. Either way, it is not what your tomcat expects (unless it
is *also* the default server for connections to this address).

And getting nginx to insert the Host header you want is one way to approach it.
