We are facing a deployment/tunneling issue with the forge application which is built using custom UI. App shows as deployed during the deployment and accessible only when connected through tunnel (using forge tunnel at terminal).
Issue:
Whenever the tunnel is disconnected, the deployed app is inaccessible at admin page by the admin /developer user.
If the forge tunnel is disconnected from the sandbox environment, then the app, if accessed, shows a blank page.
Configurations:
