Ngrok error when Previewing

Hello, I recently just installed and ran the quickstart-react package via Command Prompt.
Everything managed to install itself successfully and running it was just as smooth.

But as soon as I got my URL from http://localhost:4040/status and pasted it into the preview section of my app this showed up.

Is this normal?
Do I have to create a ngrok account?
