About the pyscript example Simple Clock

When I download the pyscript example (simple_clock.html) to my PC and run it, it runs. However, when I upload it (simple_clock.html, utils.py ) to the my server, I get an error as below.

(PY0500): Fetching from URL ./utils.py failed with error 500 (Internal Server Error). Are your filename and path correct?

Why does not work on my server?

simple_clock.html
https://pyscript.net/examples/simple_clock.html

utils.py
https://pyscript.net/examples/utils.py

It works after change the Server setting.
