No request.When I tried to access port 42001 in my browser, it took a long time to respond

There is a similar issue here #1020
According to the op, it is caused by a virtual environment. Can you test whether this is the case for you as well?

This may not be the case. I am running a packaged pyinstaller application. no virtual environment

Sounds like this might be caused by the default single-threaded server. Maybe switching to paste or similar would help. https://bottlepy.org/docs/dev/deployment.html#server-options

Would you able to give it a go?

Would you able to give it a go?

   server.thread = threading.Thread(
            target=lambda: bottle.run(app=app, port=server.port, quiet=not _debug['mode'], server='cheroot'),
            daemon=True)

According to the documentation, after setting multithreading mode, it worked fine ，Thank you

I have implemented a simple multithreaded server in https://github.com/r0x0r/pywebview/tree/multithreaded-server branch. @geekzsp would you be able to test it and see if it solves the problem?
