For this, you probably want "location /host1/" (with the trailing /).

What does "not working" mean here?

You make one specific request; you want to get one specific response;
but you get a different response instead?


I suspect that things will be simpler if you are happy to reconfigure
all of the "webmin" instances so that they believe they are installed
at the same place in the url hierarchy as the external users see. That is:

* add the line webprefix=/host1 to /etc/webmin/config on host1
* add the line webprefix=/host2 to /etc/webmin/config on host2

and then change your config to only use one trailing slash like so:

  location /host1/ {
    proxy_pass https://host1.local.domain:10000;


And if there is still a problem, if you can show the request/response that
does not do what you expect, it may be simpler for others to understand
and help.

Cheers,
