A new page with an automatically generated URL opens up, but it doesn't work
Trying to append :3000 to the current URL or generated URL, but this doesn't work either
Click on "Ports" in the editor and on "Forward a port", enter 3000. You will get the error message: "unable to forward localhost:3000. the host may not be available or that remote port may already be forwarded"
Description Port forwarding seems to be broken.
