Could not connected to Flet server in 30 seconds. #2759

exact duplication of error #1359 /flet-dev/flet/issues/1359

Description

When trying to start any flet app with web browser view it hangs for 30 seconds and then fails with an exception: Exception: Could not connected to Flet server in 30 seconds.. Running the same app in desktop mode works fine.

Code example to reproduce the issue: `import flet as ft

def main(page: ft.Page): page.add(ft.Text(value="Hello, world!"))

ft.app(target=main, view=ft.WEB_BROWSER)`

I get an error:

Traceback (most recent call last): File "c:\My_prog\Flet\1.py", line 12, in ft.app(target=main, view=ft.WEB_BROWSER) File "c:\My_prog\Flet.venv\Lib\site-packages\flet_runtime\app.py", line 91, in app app_sync( File "c:\My_prog\Flet.venv\Lib\site-packages\flet_runtime\app.py", line 128, in __app_sync conn = connect_internal_sync( ^^^^^^^^^^^^^^^^^^^^^^^^ File "c:\My_prog\Flet.venv\Lib\site-packages\flet_runtime\app.py", line 385, in __connect_internal_sync conn.connect() File "c:\My_prog\Flet.venv\Lib\site-packages\flet\sync_websocket_connection.py", line 63, in connect raise Exception( Exception: Could not connected to Flet server in 30 seconds.

This issue occurs when a config.ini file exists in the current working directory from which the app is started. app works fine after this file is deleted.

I have the same issue, have you resolved it @algotrading-py? I tried to change the websocket's endpoint path, but it didn't help.
