How can I figure out why and how to fix the 2GB upload file size limit I'm hitting? I can upload any size file just under 2GB but anything above fails almost instantly with the following error:

Communication failed. You may be offline, please check your connection.

I am on a Windows 2022 server and I have the root folder setting set to not restrict file size or file type. I also have an NGINX reverse-proxy in front of FileVista.

Adding the following two lines to the `/` location seems to have fixed the issue:

proxy_buffering      off;
client_max_body_size 0;
