flet publish main.py or flet build web --project main -v (2003, "Can't connect to MySQL server on 's16.link-host.net' (timed out)")

If I run flet run '.\main.py' then everything works fine.
but if I do 'flet publish main.py' and 'run python -m http.server --directory .\dist'
I follow the link 'http://localhost:8000/'
the program starts but I get an error from the console browser
(2003, "Can't connect to MySQL server on 's16.link-host.net' (timed out)")

Flet version (pip show flet):

Name: flet
Version: 0.21.2
Summary: Flet for Python - easily build interactive multi-platform apps in Python

Requires: cookiecutter, fastapi, flet-runtime, packaging, qrcode, uvicorn, watchdog
Required-by:

Python 3.12.2 (tags/v3.12.2:6abddd9, Feb  6 2024, 21:15:12) [MSC v.1937 32 bit (Intel)] on win32

Give your requirements.txt file (don't pip freeze, instead give direct packages):
flet
micropip
websockets
wsproto
peewee
pymysql

(The database is working and can be connected and tested.)

Operating system:

Windows 11,

on the server side where the database is installed
Apache | 2.4.37-62.module_el8.9.0+3646+acd210d0,
MySQL | 8.0.32-1.module_el8.8.0+3567+56a616e4,
PHP | 7.2.24-1.module_el8.3.0+2010+7c76a223,
Perl | 5.26.3-422.el8.0.1,
Kernel | 4.18.0-513.9.1.el8_9.x86_64

Start by reproducing the supplied main.py with flet publish main.py and flet build web, comparing it with the working flet run command. Inspect the published web runtime and the listed peewee, pymysql, and micropip dependencies to determine where the MySQL connection fails. Done requires a confirmed cause and an agreed fix or documented limitation.
