Portainer.io One-click deploy with caprover does not work well

Question

I am trying to deploy a Portainer.io with Caprover using the One-click Apps. I followed all the instructions and filled the name for it. At the end of setup, it tells you to activate websocket support and continue with the user interface of Portainer.

At this point, either activating Websocket Support or not, it does not connect to Portainer at my personal url. I have tried using http as well as https, but neither way it works

This is the screen it shows when I try to acces with hhtps:foo.bar.com:

I have already tried to restart the Portainer container, but it also did not worked.

What should I do different?
