Bug Report

Description

Bug Summary:
I use an Nginx proxy to handle SSL connection to openUI.
If I try to upload a document exceeding the max value configured in Nginx, on WebUI interface, nothing shows that an error occured. As an enduser, I'll wait undefinitely, I'm still seeing the "work in progress" animation, even if the web console shows that the server answered with an HTTP 413 error

Steps to Reproduce:
Use a Nginx proxy between the user browser and OpenWebUI application.
Try to upload a file exceeding Nginx configuration

Expected Behavior:
An error should be seen on the interface, saying that the file is too large

Actual Behavior:
No error is shown, the picto animation for a file upload is seen undefinitely
