On Windows, trailing dot is not significant and is ignored by
filesystem accesses, so it is normalized away. See here for more
details:

If you want nginx to preserve URI of a request exactly as it was
provided by the client - make sure to use proxy_pass without an
URI compontent, that is:

location / {
proxy_pass http://backend;
}

Note no trailing "/" after "backend".
