If the front-end is deployed independently and the chainlit back-end is connected, the connection may be disconnected

We modified the front-end code, started the front-end with pnpm run dev, and connected the chainlit backend with the command chainlit run app.py. But unfortunately, we found that the front end always appeared disconnected after a period of time, and the "resume" button appeared in the position of the input box on the page. How can I solve it?
