Need some help please.  I have Odoo v16 running on our Windows 2019 server but not using it through IIS.  My goal is to use nginx instead of IIS for the reverse proxy along with SSL but keep running into a roadblock.  I have used several nginx.conf examples, including those found on the forum here but, it continues to generate the error "2023/02/21 16:49:46 [emerg] 10816#2748: "upstream" directive is not allowed here in C:\nginx/conf/nginx.conf:1".  Almost all other examples of setup with nginx are related to Ubuntu & after parsing through their examples, they are pretty much along the same configuration as the couple Windows examples.  Does anyone else have Odoo installed on Windows and using nginx that will share with me their configuration files and/or instructions?
