Hot reloading not working in Development Mode

Hey,
I am developing a custom component and my hot reloading is no longer working. I have tested it with old components where it previously worked, but with a new one, there was no success. Does anyone have an idea what could be causing this?

Thanks

Edit: I fixed it, its actually visible in this Video: https://youtu.be/erhzQbhBvJI?t=1290 - you have to allow “localhost”, “127.0.0.1” and your local ip address to exchange the data, i only allowed to local ip address

A wild guess is that it may be a problem between the editor beying on https protocol while the dev server is on http, it has always been annoying.
Maybe someone from the team can tell what’s the problem
