Hallo,
Bern93 : getestet. Funktioniert eigentlich alles wie in der Doku beschrieben.
nginx Konfiguration: /etc/nginx/sites-available:
##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# https://www.nginx.com/resources/wiki/start/
# https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/
# https://wiki.debian.org/Nginx/DirectoryStructure
#
# In most cases, administrators will remove this file from sites-enabled/ and
# leave it as reference inside of sites-available where it will continue to be
# updated by the nginx packaging team.
#
# This file will automatically load configuration files provided by other
# applications, such as Drupal or Wordpress. These applications will be made
# available underneath a path with that package name, such as /drupal8.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

# Default server configuration
#
server {
listen 80 default_server;
listen [::]:80 default_server;
# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.

# Read up on ssl_ciphers to ensure a secure configuration.

Das ist die OOTB Konfiguration (unter Ubuntu), erweitert um zwei `location` Direktiven.
Die App namens `counter.py':
import os
import flet as ft
DEFAULT_FLET_PATH = '' # or 'ui/path'
DEFAULT_FLET_PORT = 8502
def main(page: ft.Page):
page.title = "Flet counter example"
page.vertical_alignment = ft.MainAxisAlignment.CENTER
txt_number = ft.TextField(value="0", text_align=ft.TextAlign.RIGHT, width=100)
def minus_click(e):
txt_number.value = str(int(txt_number.value) - 1)
page.update()
def plus_click(e):
txt_number.value = str(int(txt_number.value) + 1)
page.update()
page.add(
ft.Row(
[
ft.IconButton(ft.icons.REMOVE, on_click=minus_click),
txt_number,
ft.IconButton(ft.icons.ADD, on_click=plus_click),
],
alignment=ft.MainAxisAlignment.CENTER,
)
)
if __name__ == "__main__":
flet_path = os.getenv("FLET_PATH", DEFAULT_FLET_PATH)
flet_port = int(os.getenv("FLET_PORT", DEFAULT_FLET_PORT))
ft.app(name=flet_path, target=main, view=None, port=flet_port)

Python-App starten via python3 counter.py
Fertig. Der Aufruf von `http://localhost` liefert die Defaultseite von nginx, der Aufruf von `http://localhost/app` auf dem Rechner, wo das läuft. Von einem anderen Rechner im gleichen Netz funktioniert das auch über die IP-Adresse des Host-Rechners. ABER: wenn ich diese Seite über Safari (iOS oder iPadOS) aufrufe, kommt die Seite zwar, aber ich sehe nur einen Platzhalter für das Flet Logo im Ladebildschirm, mehr passiert nicht.
Ob das irgendwie an Sicherheitseinstellungen von iOS oder den Websockets oder was auch immer liegt - keine Ahnung.
