Quasar in production - Refresh - 404 Not Found

[Cabezagithub]

I have a Quasar SPA in production and when I try to refresh (F5) I get the following error: 404 Not Found.
The SPA is deployed on Ubuntu 20.04 with Nginx.
Build the SPA on Windows 11. I compiled with Quasar build and uploaded the files. Running "Quasar dev" on my Notebook I have no problems with refresh (F5), everything works fine.
The first installation in production had Apache2 installed, I stopped it and installed Nginx but the problem persists, so I think it must be a Quasar configuration that I don't have correctly.
It's driving me crazy... Any suggestions?

Is the 404 Not found error given by the browser, or is the 404 framework page shown?

404 Not Found

nginx/1.18.0 (Ubuntu)

It shows in the browser.

Could you try to create static html file test.html and verify thats it is visible from browser?
Because it seems be a Web server issue, not application problem.

set your server for vue router history mode https://router.vuejs.org/guide/essentials/history-mode.html#nginx

Excellent Metalsadman ... good, good.
It is not an error, it is a configuration of the Web Server.
Really thank you.
