Ngrok Tunnel from Google Colab not working

[claudineisbezerra]

Hi everyone, I'm just getting started with Google Colab and NGrok to test an application, and I'm using a basic Flask example.

I've initiated a tunnel using an auth token, and when I visit https://dashboard.ngrok.com/tunnels/agents, I can see that the tunnel has started successfully. It looks like ngrok and pyngrok are doing what they're supposed to do.

It seems like there might be some issue with the origin of Colab being blocked and it's not possible to access the expose URL. Does anyone have a simple working example they could share with me?
