Hi there,

Thanks for the pictures in your previous reply; they do give a bit of
a hint as to what is going on.

The "after-login" picture shows that /session_login.cgi does not exist
on nginx -- that is to be expected, because you want that link to go to
/vml000032/session_login.cgi instead. (Otherwise, you would not be able
to have two separate webmin instances in different places.)

It appears to be the case that webmin is not especially straightforward
to reverse-proxy at a non-root url.

From the various web pages listed, it looks like there may be different
versions of webmin that do different things.

So if you are happy to keep testing and trying, there are perhaps a few
more things that you can try.

The linked web page seems to suggest that you want

location /vml000032/ { # with the trailing /
proxy_pass http://192.168.1.32:10000/; # with the trailing /
proxy_set_header Host $host;
proxy_redirect http://$host:10000/ /vml000032/;
}

I suspect that you either want both of the last two lines, or neither
of them. You may be better of with neither; only testing will show.

That looks like it has a chance of working, so long as webmin is not
running with ssl.

Maybe webmin config also can use

relative_redir=1

And it may be useful to edit miniserv.conf so that it includes

cookiepath=/vml000032

I suspect that that is because you used the line

proxy_set_header Host $host;

When the rest is working, you can perhaps try to log in using credentials
that are different on the two servers, and see which lets you in.

Good luck with it,
