'GET /' cannot be proxied to UiAutomator2 server

Pycharm version: 2020.3.3
Appium Desktop version: 1.20.2
Node.js version: 12.8.1

Today, after running the code in Pycharm I clicked the button for refreshing source in Appium, what happens is that the app fails to perform any action.
How to fix it? What could I do for it?
